Question 15 How many grams of NaCl are required to make 500.0 mL of a 1.500 M solution? 58.40 g 175.3 g 14.60 g 43.83 g

Answer 1

Hi!

To make 500 mL of a 1,500 M solution of NaCl you'll require 43,83 g

To calculate that, you will need to use a conversion factor to go from the volume of the 1,500 M solution to the required grams. For this conversion factor, you'll use the definition for Molar concentration (M=mol/L) and the molar mass of NaCl. The conversion factor is shown below:


`gNaCl=500mLsol* (1L)/(1000 mL)* (1,500 mol NaCl)/(1Lsol)* (58,4428 g NaCl)/(1 mol NaCl) \\ =43,83gNaCl`

Have a nice day!
