What is the molarity of a solution that contains 0.202 mol kcl in 7.98 l solution?

Explanation:

1) Data:

a) M = ?

b) Solute: KCl

c) n = 0.202 mol

d) V = 7.98 liter

2) Principles and formulae:

a) Molarity is the number of moles of solute per liter of solution. The units of molarity are mol/liter, which is equivalent to M.

b) M = n / V (in liter)

3) Solution:

Substitute the data into the equation M = n / V (in liter)

Since the number of moles and the volume are expressed with 3 significant figures, the answer is given with the same number of significant digits.
