The molar mass of two moles of CaCO3 is 2 mol × 100.09 g/mol = 200.18 g. b. CH4 = 16.05 amu; O2 = 32 amu; CO2 = 44.01 amu c.
What are the Formula mass and molar mass of 1 mole of caco3?
Based on the chemical formula, we have 2 atoms of Li, so the atomic weight of Li has to be multiplied by 2 to obtain 13.88 g/mol.
What is the mass of CaCO3?
Solution — Molecular mass of CaCO3= 40+12+3×16 = 100 No. mole of CaCO3 = 50g/100g = 0.5 0.5 mole of CaCO3 contains 1.5 moles of oxygen atoms No. of oxygen atoms = 1.5 × 6.022×1023 = 9.033×1023 atoms Mass of Oxygen atoms = 1.5 × 16 = 24 g.
