French Toast #27a

Postby Cindy Nguyen 1L » Wed Jun 13, 2018 11:46 pm

In a sicence lab, you created a stock soluiton of 1.50 M Na2O.
How many milliliters of this stock solution would you need to make 210 mL of a .550 M Na2O solution?

How do you go about solving this?

For part A, use the equation m1v1=m2v2. So 1.50*v1=(.550m)(210mL), v1=77mL.

For part B, use pH+pOH=14-(-log[OH-]), so pH=14.04.
