Chemistry

Using Stoichiometry,calculate the mole quantity of hydrogen gasproduced for each data point in Part A and Part B of thisexperiment using your data. Identify the concentration of HCl (partA) or mass of magnesium (part B)for when the limiting reactantchanges. All calculations must be shown.
Part A
1. )0.250 g Mg
2. )0.50 M
3. )1.0 M
4. )1.5 M
5.) 2.0 M
6.) 2.5 M
7.) 3.0 M
8.) 3.5 M
PART B
1. 2.0 M HCl -Entre moles of calculated moles of H2 (g) fromPart A.
2. 0.050 g
3. 0.10 g
4. 0.15 g
5. 0.20 g
6. 0.25 g -enter moles of calculated moles of H2 (g) from PartA.
7. 0.30 g
8. 0.35 g
9. 0.40 g

PLEASE HELP! Even if you could just explain the process for justone of them that would be helpful. I assume once you get the firstone the other ones should follow the same method of solving. Iwould really appreciate anyone's help as soon as possible.

The reaction is Mgs 2HCl MgCl2 H2g so each mole of Mg will react with two moles of HCl to give one mole of H2 In each reading we have to calculate Moles of Mg Mass of metal atomic weight Moles See Answer
