Front

Define molar mass.

Back

The mass of one mole of a substance, typically expressed in grams per mole (g/mol).

Front

What is the ideal gas law equation?

Back

PV = nRT, where P is pressure, V is volume, n is number of moles, R is the ideal gas constant, and T is temperature.

Front

How do you convert grams to moles?

Back

Moles = mass (g) / molar mass (g/mol).

Front

What is the relationship between moles and volume at STP?

Back
