Question

calculate the number of moles in 112kg of iron​

Answer 1

Answer:

1. (a) 1 mole of iron (Fe) = 56 g (molar mass)
2. Since 56 g of iron = 1 mol.
3. Therefore, 112 g of iron= 1/ 56 ×112 mol = 2 mol.
4. (b) Molar mass of C12H22O11 = (12 × 12) + (22 × 1) + (11 × 16) = 342 g.
5. Since mass of 1 mole of sugar = 342 g of sugar.
6. Therefore mass of 0.5 mole of sugar = 342 × 0.5 = 171 g.
