Question

How many grams of NaCl are needed to make 0.800 liter of a 5.00 M solution?

Answer 1

0.324 g is required to make 5.00 M solution of NaCl in 0.800 L.

Given data:

Molarity = 5.00 M

Formula Mass = 58.5 g/mol

Required volume = 0.800 L

To Find;

Mass in gram = ?

Solution:

Formula for calculating mass in gram is given as,

Mass in gram = Molarity × Formula mass × Volume required / 1000 putting values

Mass in gram = 5.00 M × 58.5 g/mol × 0.800 L / 1000

Mass in gram = 0.234 g
