Homework Help: Chemistry 101

Posted by Kelsey on Monday, February 22, 2010 at 5:40am.

I don't remember my instructor going over this and the book isn't explaining it very well. Can anyone help answer these?

Indicate the concentration of each ion or molecule present in the following solutions.

1. 0.30 M NaNO3
2. 1.5x10^-2 M MgSO4
3. 2.00x10-2 M C6H12O6
4. A mixture of 45.0 mL of 0.272M NaCl and 65.0 mL of 0.0247M (NH4)2CO3. Assume that the volumes are additive.

Thank you for the help!
