can you please give me the formulae on finding the number of moles and mass?
This is often referred to as the molar mass.
Carbon weighs 12.01 g/mole
Oxygen weighs 16.00 g/mole
1 mole of a pure substance has a mass in grams equal to its molecular mass (MM).
eg, 1 mole of Helium (a monatomic gas with the formula He) has a mass equal to its relative atomic mass, 4.003g
eg, 1 mole of hydrogen gas (a diatomic gas with the formula H2) has a mass equal to 2 x 1.008 = 2.016g
eg, 1 mole of ammonia gas (NH3) has a mass equal to 14.01 + (3 x 1.008) = 17.034g
eg, 1 mole of water (H2O) has a mass equal to (2 x 1.008) + 16.00 = 18.016g
