Finally click on calculate. N M V Example. Convert the moles of substance to desired units of measure.

Pump gas molecules to a box and see what happens as you change the volume add or remove heat and more. Because the volume and temperature are the same for each sample in the gas not to mention each molar value is multiplied by the same constant we can use the distributive property of mathematics to rewrite the equation as P total 04 0. 1 mole of Ar 6.

We can then use the calculated molar mass to convert between mass and number of moles of the substance.
