Calculate the moles and the mass of solute in 250.0 ml of 6.00 m naoh

If it is 6.00 M (molar) NaOH, there are 6 moles per liter. Use this equation to find the amount of moles in 250 mL

Molarity x Liters = Moles

We have the molarity already (6.00 M), so we just need to convert mL to L.

250 mL x 1 Liter/1000 mL =.25 L

Set up the equation

6.00 M x. 25 L = 1.5 moles
