Moles and Mass, Determine the number of grams in each of the quantities below.?

1.) 2.5 moles of NaCl

2.) 0.50 moles of H2SO4

3.) 1.70 moles of KMnO4

4.) 0.25 moles of KCl

5.) 3.2 moles of CuSO4•5H2O

Answer:
Grams = Molar Mass x # of Moles

1) Molar Mass of NaCl=58.453 g/mol
2.5 x 58.453 = 146.133 grams of NaCl

2) Molar Mass of H2SO4 = 98.065 g/mol
0.5 x 98.065 = 49.032 grams of H2SO4

3) Molar Mass of KMnO4 = 158.838 g/mol
1.70 x 158.838 = 270.025 grams of KMnO4

4) Molar Mass of KCl = 74.453 g/mol
0.25 x 74.453 = 18.613 grams of KCl

5) Molar Mass of CuSO4.5H2O = 249.611 g/mol
3.2 x 249.611 = 798.755 grams of CuSO4.5H2O
1) 145
2) 49.05
3) 268.6
4) 18.65
