Homework Help: college chemistry - molarity question

Posted by lholmq on Wednesday, April 29, 2009 at 1:23am.

My textbook doesn't show me how to do problems like the following, and I'm having a hard time finding similar problems online. Most of the molarity problems I'm finding involve mixing a substance with water, but these involve mixing moles of substances with moles of other substances and I'm confounded as to how to try to solve them. If anyone can show me steps to solve these two, I would be extremely grateful:

1) If 35 mL of 2.0 M H2SO4 is mixed with 35mL of 1.0 M NaOH, how many moles of H2SO4 remain after completion of the reaction?

2) What is the molarity of Ca(NO3)2 in a solution resulting from mixing 150.0 mL of 0.0200 M HNO3 with 150.0 mL of 0.0100 M Ca(OH)2?

Thank you so much. :)
