The mass of the substance is the product of the moles and the molar mass. The mass of sulfur = 80 gm, calcium = 72 gm, carbon = 6 gm, and copper = 201.6 gm.
What is mass?
Mass of any substance is the amount of the constituent particle it holds together and can be measured in grams. The mass has been calculated from the moles of the substance and its molar mass.
The mass of sulfur is calculated as,
Mass = moles × molar mass
= 2.50 mol × 32 g/mol
= 80 gms
The mass of calcium is calculated as,
Mass = moles × molar mass
= 1.80 mol × 40 g/mol
= 72 gms
The mass of carbon is calculated as,
Mass = moles × molar mass
= 0.50 mol × 12 g/mol
= 6 gms
The mass of copper is calculated as,
Mass = moles × molar mass
= 3.20 mol × 63 g/mol
= 201.6 gms
