Question

Can someone help me with numbers 3-5 it's been ages since I've done Gen Chem and can't seem to figure these out. http://i57.tinypic.com/w06zjb.jpg

3) how many mL of 3M h2so4 are required to prepare 6 L of 0.005 M h2so4?

4) what would be the concentration of the diluted solution from problem #3 expressed in mM,uM,and nM ( use scientific notation where appropriate) ?

5) A solution contains 10g of glycine MW =75.07 in a total volume of 75mL . express the concentration in terms of g/L , %w/V , and mM.

Explanation / Answer

3)(0.005*6)/3 *100 = 10 ml

4)Concentration= 8.33 mM

= 8333.33 uM

=8333333.33 nM

5)molarity=(10/75.07)*(1000/75)=1.77 M=1777 mM

=(10/75)*100=13.33 %w/v

=0.133 g/L
