find the mass of the following
1)0.003moles of magnesium
2)0.2moles of ammonia
3)0.25moles of nitric 5 acid
1) The molar mass of magnesium is 24.31 g/mol.
Mass = moles x molar mass
Mass = 0.003 mol x 24.31 g/mol
Mass = 0.073 g
The mass of 0.003 moles of magnesium is 0.073 g.
2) The molar mass of ammonia is 17.03 g/mol.
Mass = moles x molar mass
Mass = 0.2 mol x 17.03 g/mol
Mass = 3.406 g
The mass of 0.2 moles of ammonia is 3.406 g.
3) The molar mass of nitric acid is 63.01 g/mol.
Mass = moles x molar mass
Mass = 0.25 mol x 63.01 g/mol
Mass = 15.753 g
The mass of 0.25 moles of nitric acid is 15.753 g.
