Question

50.0 ml sample of 0.108 m h2so4 is diluted to 250.0 ml. what is its new molarity?

Answer 1

The new molarity is 0.0216 M

What is molarity?

The quantity of solute molecules per liter of solution is known as a solute's molarity or molar concentration. Sometimes the chemical formula of the solute is enclosed in square brackets to indicate the molar concentration of the solute. We may translate between the volume of the solution and the moles (or mass) of the solute using molar concentration.

Given :

Volume of sample used = 50 mL

molarity of H2SO4 used = 0.108 M

final volume of the solution = 250 mL

formula used :

M1 x V1 = M2 x V2

where ,

M1 = molarity before dilution

V1 = initial volume

M2 = molarity of final solution

V2 = volume of the final solution

Solution:

M2 = M1 x V1 / V2

= > M2 = 0.108 x 50 / 250 = 0.0216

Therefore, the molarity of the final solution is 0.0216 M
