Molecular Weight Calculator (Molar Mass)

Molecular mass or molar mass are used in stoichiometry calculations in chemistry. In related terms, another unit of mass often used is Dalton (Da) or unified atomic mass unit (u) when describing atomic masses and molecular masses. It is defined to be 1/12 of the mass of one atom of carbon-12 and in older works is also abbreviated as "amu".

What mass of CO2 will be produced when 50 g of CaCO3

The first thing to do here is to calculate the relative formula mass of CaCO 3 and CO 2. RFM of CaCO 3 = 40 g + 12 g + (16 g x 3) = 100 g. RFM of CO 2 = 12 g + (16 g x 2) = 44 g. The decomposition equation shows 1 CaCO 3 goes to 1 CaO and 1 CO 2. We have 50 g of CaCO 3, effectively we have half a CaCO 3. 50 g / 100 g = 0.5
