3-Yep, youre right!2.5lb * 453 g = 1132.1132.5 * 22.......
Calculate the number of liters of hydrogen gas that oculd be prodcued by reacting by 2.50 lbs of pure magnesium metal with an excess of hydrochloric acid at STP.
Mg + 2HCl ----> MgCl2 + H2

This is what I got let me know if I am wrong and where I messed up

25lbs * 453.6g/1 lbs * 1m/24.3g * 22.4L/1m = 10453.3

Yep, you're right! Just include my short explanation :)
Mg + 2HCl ----> MgCl2 + H2

2.5lb * 453 g = 1132.5g
1132.5 * 22.4/ 24 = 1057 litter
