im not sure how u solve these types of problems...

How many moles of NaOH are contained in 200ml of a 0.1M of NaOH?

How many grams of NaOH are contained in 500ml of a .5M solution of NaOH?

<<How many moles of NaOH are contained in 200ml of a 0.1M of NaOH? >>

A 0.1 M solution has 0.1 moles of the solute NaOH per liter. You have 0.2 liters. The answer is therefore 0.1 x 0.2 moles.

Do the second problem similarly to get the numner of moles of NaOH, and then multiply by the molecular weight of NaOH to get the answer in grams of NaOH.
