Answer #1

1)

Molar mass of HCl,

MM = 1*MM(H) + 1*MM(Cl)

= 1*1.008 + 1*35.45

= 36.458 g/mol

mass of HCl = 9.19 g

mol of HCl = (mass)/(molar mass)

= 9.19/36.458

= 0.2521 mol

According to balanced equation

mol of H2 formed = (1/2)* moles of HCl

= (1/2)*0.2521

= 0.1260 mol

Answer: 0.1260 mol
