Answer to Question #293786 in Physical Chemistry for Roman

Question

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

In the above equation, how many grams of water can be made when 18.5 moles of HNO₃ are consumed?

 

Round your answer to the nearest tenth. If you 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.:

Answer 1

Mole ratio HNO$_3:$ H₂O $=8:4$

Moles of water $=\frac{18.5}{8}×4$

$=9.25$ moles

Mass $=9.25×18$

$=166.5g$
