You want how many moles?
moles = M x L = 1.50 x 0.1 = 0.150 moles.
How many grams is that?
moles = grams/molar mass; therefore, g = moles x molar mass and 0.10 moles x molar mass = ??
Take ?? g NaCl, place in a 100 mL volumetric flask, add some water, swirl until all of the solute is dissolved, then make to the mark on the volumetric flask with DI water.
