Hydrogen gas is prepared in the laborato...

Hydrogen gas is prepared in the laboratory by reacting dilute HCl with granulated zinc, Following reaction takes place
`Zn+2HClrarrZnCl_(2)+H_(2)`
Calculate the voluem of hydrogen gas liberated at STP when 32.65 g of zinc reacts with HCl. 1 mol of a gas occupies 22.7 L volume at STP, atomic mass of Zn=65 .3u

Text Solution

Verified by Experts

1 mole of Zn, i.e., 65.3 g produced 1 mole of `H_(2)`, i.e., 22.7 L or STP
`therefore" 32.65 g of Zn will produce "H_(2)" at sTP"=(22.7)/(65.3)xx32.65=11.35L`
