What is the molarity of the solution formed by mixing 0.20mol of sodium hydroxide with enough water to make 150 ml of solution?

1 answer:

3 0

Molarity is defined as the number of moles of solute in 1 L of solution
number of NaOH moles present - 0.20 mol
volume of solution - 150 mL
since molarity is taken as number moles of solute in 1000 mL
if 150 mL contains - 0.20 mol
then 1000 mL should contain - 0.20 / 150 x 1000 = 1.33 mol
therefore molarity is 1.33 M

Explanation:

According to the ideal gas equation, PV = nRT.

where, P = pressure, V = volume

n = no. of moles, R = gas constant

T = temperature

Also, density is equal to mass divided by volume. And, no. of moles equals mass divided by molar mass.

Therefore, then formula for ideal gas could also be as follows.

P = $\frac{mass}{volume \times molar mass} \times RT$

or, P = $\frac{density}{\text{molar mass}} \times RT$

Since, density is given as 0.789 g/ml which is also equal to 789 g/L (as 1000 mL = 1 L). Hence, putting the given values into the above formula as follows.

P = $\frac{density}{\text{molar mass}} \times RT$

= $\frac{789 g/l}{46.06 g/mol} \times 0.0821 L atm/mol K \times 373 K$
