Question

What is the molarity of a solution prepared by dissolving 0.217 mol of ethanol, C2H5OH, in enough water to make 100.0 mL of solution

Answer 1

Answer: 2.17mol/L

Explanation:

C=n/V

n: 0.217mol

V: 100.0mL

1. Convert mL to L (100.0mL/1000 = 0.01L)

2. Put numbers into equation (C= 0.217/0.01L)

3. Molarity is 2.17mol/L
