### Stoichiometry

Problem Mg + HCL MgCl2 + H2What volume of hydrogen is produced from the reaction of 50.0g of mg and the equivalent of 75g of HCL?

What do you think goes first?

Balance equation

Pray

1 mol Mg 1 mol H2

What volume of hydrogen is produced from the reaction of 50.0g of mg and the equivalent of 75g of HCL?

Mg + 2HCL MgCl2 + H2
