The mass in grams of 6.25 mol of copper (II) nitrate is 1171.88g
HOW TO CALCULATE MASS:
- The mass of a substance can be calculated by multiplying the number of moles by its molar mass. That is;
- mass (g) = no. of moles (mol) × molar mass (g/mol)
- copper (II) nitrate has a chemical formula of Cu(NO₃)₂, hence, the molar mass can be calculated as follows:
- Cu(NO₃)₂ = 63.5 + {14 + 16(3)}2
- mass of Cu(NO₃)₂ = 6.25 × 187.5
- mass of Cu(NO₃)₂ = 1171.88g
- Therefore, the mass in grams of 6.25 mol of copper (II) nitrate is 1171.88g.
