3 Cu + 8HNO3 --> 3 Cu(NO3)2 + 2 NO + 4 H2O

Question

In the above equation, how many grams of water can be made when 10 grams of HNO₃ are consumed?

Round your answer to the nearest tenth. If your answer is a whole number like 4, report the answer as 4.0

Use the following molar masses. If you do not use these masses, the computer will mark your answer incorrect.:

Element Molar Mass

Hydrogen 1

Nitrogen 14

Copper 63.5

Oxygen 16

Answer 1

10 g HNO3 / (63 g per mol HNO3) = .1587 mole HNO3

.1587 MOL HNO3 x 4 mol H20/8 mol HNO3 = 0.0793 mol H20

.0793 mol2 H20 x 18 g/mol of H20= 1.428 grams of H20 produced or 1.43
