Due to having low atomic mass and large atomic radius, sodium is third-least dense of all elemental metals and is one of only three metals that can float on water, the other two being lithium and potassium. It is a good conductor of electricity and heat. Sodium metal can be easily cut with a knife. Bulk sodium is usually stored in oil or an inert gas. Sodium at standard temperature and pressure is a soft silvery metal that combines with oxygen in the air, forming sodium oxides. In nerve cells, the electrical charge across the cell membrane enables transmission of the nerve impulse-an action potential-when the charge is dissipated sodium plays a key role in that activity.Ĭharacteristics Physical Emission spectrum for sodium, showing the D line Isotonic loss of water and sodium from the ECF compartment decreases the size of that compartment in a condition called ECF hypovolemia.īy means of the sodium-potassium pump, living human cells pump three sodium ions out of the cell in exchange for two potassium ions pumped in comparing ion concentrations across the cell membrane, inside to outside, potassium measures about 40:1, and sodium, about 1:10.

Loss of water from the ECF compartment increases the sodium concentration, a condition called hypernatremia. Sodium ions are the major cation in the extracellular fluid (ECF) and as such are the major contributor to the ECF osmotic pressure and ECF compartment volume. Sodium is an essential element for all animals and some plants. Among many other useful sodium compounds, sodium hydroxide ( lye) is used in soap manufacture, and sodium chloride ( edible salt) is a de-icing agent and a nutrient for animals including humans. Sodium was first isolated by Humphry Davy in 1807 by the electrolysis of sodium hydroxide. Many salts of sodium are highly water-soluble: sodium ions have been leached by the action of water from the Earth's minerals over eons, and thus sodium and chlorine are the most common dissolved elements by weight in the oceans. Sodium is the sixth most abundant element in the Earth's crust and exists in numerous minerals such as feldspars, sodalite, and halite (NaCl).

The free metal does not occur in nature and must be prepared from compounds. Sodium is an alkali metal, being in group 1 of the periodic table.

It is a soft, silvery-white, highly reactive metal. You might wanna check out our Gay-Lussac's law calculator.Sodium is a chemical element it has symbol Na (from Latin natrium) and atomic number 11. Gay-Lussac's law – The formula used when dealing with an isochoric process (a process where the volume does not change): We have a stand-alone Charles' law calculator if you are interested in knowing more. So how about giving the Boyle's law calculator a try?Ĭharles's law – The formula used when dealing with an isobaric process (a process where the pressure does not change): Try to keep your notes as simple as possible!īoyle's law – The formula used when dealing with an isothermal process (a process where the temperature does not change): Depending on the process, you may also cross out one of the following variables: T, V, P. (R is equal to the Avogadro's constant multiplied by the Boltzmann constant)Īlways remember that the nR part of any of these equations is constant – it means it may be crossed out when you transform the formula. R – The ideal gas constant = 8.314 J/(mol With just a few transformations, we can use this formula to determine all the properties of a given gas in three types of processes: isobaric, isochoric, and isothermal.īelow you will find all of the most essential, ready-to-go equations used in all those calculations, along with a quick explanation.

That's why we use the combined gas law calculator (a.k.a. There are plenty of chemistry-based queries that can be solved by some form of the original ideal gas law. The molar mass of gas is not the only thing we can calculate with the ideal gas law! A Dalton is a unit of atomic mass equal to the mass of 1/12 of a particle of carbon ¹☬. The calculated value is numerically identical to 1 u (or 1 Da = Dalton, used in biochemistry).

It's as simple as that! Recommended units:īut your mass isn't given in grams? Don't worry why don't you take some time to discover how to properly convert between different densities and weights? If you want to work it out yourself, without the molar mass of gas calculator, be careful with the units! This particular equation uses a constant of 0.0821, which is intended for the following units: Moles = (Pressure × Volume) / (0.0821 × Temperature) Our gas law calculator uses the following equations:

Mass (not required for number of moles calculations).

Volume of the gas (ml, L, dm³, m³) and.

Pressure (most commonly used units: atm, kPa).

You need the following data about the gas:
