The volume of 8 g of hydrogen gas is .... cm3 at STP.
12g of me on the reacting with acid gives hydrogen gas the volume of which at stp is
Hydrogen gas is prepared in the laboratory by reacting dilute HCl with granulated zinc. Following reaction takes place
Zn+2HCl→ZnCl2+H2
Calculate the volume 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
