Question

If a 6.00M solution of sodium hydroxide occupies 520 mL of space how many grams of NaOH is dissolved in the solution? (Remember M = moles/L). And the work.

Answer 1

M = moles/L
You have M and L, solve for mols.

Then moles = grams/molar mass
You have moles and molar mass, solve for grams.

Answer 2

6.00M*.520L= 3.12Moles of NaOH
3.12 mols*40= 124.8 grams of NaOH
