Question

PLEASE You need to make a 0.23 M solution of NaCl using a 250 mL volumetric flask. How many grams of NaCl do you need? Round to the hundredths place (0.01)

Answer 1

Easy. You turn 250 mL into Liters which comes out to be 0.25. We now need moles so you multiply 0.25 L and 0.23 M of NaCl and you get 0.058 moles of NaCl. Now you need to turn moles into grams so 0.058 moles x 58.44 (NaCl molar mass) /1 mol and you get 3.39 grams of NaCl.
