Answer 2

Dear Student,

◆ Answer -

Molarity = 3.435 M

◆ Explanation -

# Given -

V2 = 50 cc = 50 ml

V = 250 ml = 0.25 L

M1 = 18 g/mol

M2 = 46 g/mol

# Solution -

Density of ethanol is given by -

d = W2 / V2

0.79 = W2 / 50

W2 = 50 × 0.79

W2 = 39.5 g

Molarity of ethanol solution is calculated by -

Molarity = n2 / V

Molarity = (W2/M2) / V

Molarity = (39.5/46) / 0.25

Molarity = 3.435 M

Therefore, molarity of ethanol solution is 3.435 M.

Thanks dear...
