Question

A 30.0 gram sample of NaOH is dissolved in water, and thesolution is diluted to give a final volume of 1.50L. The molarityof the final solution is a. 0.500M b. 0.750M c. 1.00M d. 2.00M e.3.00M Please explain how you got the answer. I don't even knowwhere to begin.

Explanation / Answer

molar mass of NaOH = 40g/mol
30gNaOH * (1mol/40g) = .75mol NaOH
molarity = (moles solute/liters solution)
.75molNaOH/1.5LNaOHsolution= .50M NaOH
The answer is a.
