Posted by Dylan on Sunday, November 6, 2011 at 10:18am.

I'm not sure how to do a couple of problems on my chemistry worksheet. Can you please help me?

You dissolve 0.00902 g of naOH in enough water to make 1000 mL. What is the Ph of this soultion.

What is the molarity, pH, and pOH of 5.00 of naOH in 750.0 mL of soultion. I know how to do the pH and the pOH usaully but how do I do it with the g?

Last question:
You take 2 mL of 18.0 M H2SO4 and add it to 998 mL of wate4r. What is the pH and pOH?
Can you please show me how to do these... I'm lost. Thanks
