a) 1 mol of oxygen atom = 8 g
0.2 mol of oxygen atom = 8x0. 2 = 1.6g
b) molar mass of water = 18 g.mol^-1
1 mol of water = 18 g
0.5 mol of water = 9 g
0.2 mol of oxygen atom = 8x0. 2 = 1.6g
b) molar mass of water = 18 g.mol^-1
1 mol of water = 18 g
0.5 mol of water = 9 g

The mass of mole of oxgyen atom is 16 which is the gram mole weight So for one mole of atom the weight is 16 .0.2moles of atom the weight will be 16*0.2 which is equal to 3.2grams
