2.00 M NaOH means that there are 2 moles of NaOH in each liter of solution
First, find how many moles of NaOH we have. Use this equation.
Molarity x Liters = Moles
Convert mL to L
7.58 mL x 1 Liter/1000mL = .00758 L
Set up the equation
2.00 M x .00758 L = .01516 moles
The molar mass of NaOH is 39.997 g
.01516 moles x 39.997 grams per mole = .60635452 rounded with significant figures to .606 grams of NaOH
