What is the molarity (M) of an 85.0-mL solution (total volume) containing 1.77 g of ethanol (C2H5OH)
Liono4ka [1.6K]

Answer: The molarity of solution is 0.453 M

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.

Molarity=\frac{n\times 1000}{V_s}

where,

n = moles of solute

V_s = volume of solution in ml

moles of C_2H_5OH = \frac{\text {given mass}}{\text {Molar mass}}=\frac{1.77g}{46g/mol}=0.0385mol

Now put all the given values in the formula of molality, we get

Molarity=\frac{0.0385\times 1000}{85.0}

Molarity=0.453

Therefore, the molarity of solution is 0.453 M
