Determine the total volume in milliliters of water a chemist should add if they want to prepare an 0.200 M aqueous solution with 30.2 g of NaCI? Assume the density of the resulting solution is the same as the water.
PLEASE WRITE THE EQUATION!!!!

The total volume in milliliters of water the chemist should add is 2580 mL

What is molarity?

Molarity is defined as the mole of solute per unit litre of solution. Mathematically, it can be expressed as:

Molarity = mole / Volume

How to determine the mole of NaCl

  • Mass of NaCl = 30.2 g
  • Molar mass of NaCl = 58.5 g/mol
  • Mole of NaCl = ?

Mole = mass / molar mass

Mole of NaCl = 30.2 / 58.5

Mole of NaCl = 0.516 mole

How to determine the volume

  • Mole of NaCl = 0.516 mole
  • Molarity = 0.2 M
  • Volume =?

Volume = mole / Volume

Volume = 0.516 / 0.2

Volume = 2.58 L × 1000

Volume = 2580 mL
