38. Molarity =
total volume
total mol HNO3 ; total volume = 0.05000 L + 0.10000 L = 0.15000 L
Total mol HNO3 = 0.05000 L
L
× 0.100 mol HNO3 + 0.10000 L
L
× 0.200 mol HNO3
Total mol HNO3 = 5.00 × 10−3 mol + 2.00 × 10−2 mol = 2.50 × 10−2 mol HNO3
Molarity =
0.15000 L
2.50 10 mol HNO3
× −2
= 0.167 M HNO3
As expected, the molarity of HNO3 is between 0.100 M and 0.200 M.
