How many grams of PbCl2 are produced from 1.23x10^28 moles of HCl? The answer is 1.71x10^__ Blank 5

Expert Solution

1)
2 mol of HCl reacts with 1 mol of PbBr2
Answer: 2 mol

2)
2 mol of HCl produces 1 mol of PbCl2
moles of PbCl2 produced = (1.23*10^28)/2 = 6.15*10^27 mol
Answer: 6.15*10^27 mol

3)
molar mass of PbCl2 = 207.2 + 2*35.5
= 278.2 g/mol

4)
mass of PbCl2 produced = moles * molar mass
= (6.15*10^27) * 278.2
=1.71*10^30 g
Answer: 1.71*10^30 g
