Thanks!!!PART 2)What mass of MgCl2 is produced? Answer in units of g please!PART 3) What mass of H2 is produced?......
PART 1)
One reaction that produces hydrogen gas can be represented by the unbalanced chemical equation
Mg(s) + HCl(aq) -----> MgCl2(aq) + H2 (g)
What mass of HCl is consumed by the reaction of 3.64 mol of magnesium? Answer in units of g please!

If you could answer part two and part three too that'd be great! Thanks!!!

PART 2)
What mass of MgCl2 is produced? Answer in units of g please!

PART 3)
What mass of H2 is produced? Answer in units of g please!

Thank you so much!

Balance the equation:
Mg + 2HCl --> MgCl2 + H2
Note that 1 mole of Mg consumes 2 mole of HCl and produces 1 mole of MgCl2 and 1 mole of H2.

Moles of HCl = 2 x 3.64 moles of Mg = 7.28 moles of HCl
Moles of MgCl2 = 1 x 3.64 moles of Mg = 3.64 moles of MgCl2
Moles of H2 = 1 x 3.64 moles of Mg = 3.64 moles of H2

7.28 moles of HCl x 36.46 g/mole = 265 g HCl
3.64 moles of MgCl2 x 95.22 g/mole = 347 g MgCl2
3.64 moles of H2 x 2.016 g/mole = 7.34 g H2
