Question

Suppose that you want to find the molarity of a solution that contains 15.0 g of KCI in 150.0 mL of solution.
(The molar mass of KCl is 74.45 g/mol.)
Calculate the number of moles of KCI:

Answer 1

Answer :

Moles = 0.2mol

Explanation:

n= m/M = 15/74.45 = 0.2mol

Answer 2

Answer:

A is 15.0 g

B is 74.45 g/mol

C is 0.201 mol

D is 150.0 mL

E is 1.34 M
