Determine the amount in grams needed to produce a solution of 2.50 M NaOH in 2.00 L.

200 g of NaOH

Explanation:

For this solution of NaOH

2.50 M means that in 1L of solution, we have 2.5 moles

Mol. molar mass = Mass

2.5 m. 40 g/m = 100 grams

In 1 L, we have 100 grams of solute, so in 2L, we have the double

200 g of NaOH
