molecular mass caco3=
atomic mass of carbon = 12, oxygen = 16, calcium = 40. Thus, molecular mass of CaCO3 = 40+12+16*3 = 100. This means that when you have avogadro's number (=6.022 * 10^23) of CaCO3molecules then the mass will be 100 grams.
Molar mass of H2SO4=
Molar mass of H(x2)+Molar mass of Sulphur(x1)+ Molar mass of Oxygen(x4).
This gives us,
[(1*2)+(32*1)+(16*4)]g/mol
=> [2+32+64]g/mol
=> 98g/mol.
