Respuesta :
The volume of stock solution they use to make the required solution is 6.94mL.
How we calculate the volume?
To calculate the value of required volume we will use the below equation:
M₁V₁ = M₂V₂, where
M₁ = molarity of stock solution = 18M
V₁ = volume of stock solution = to find?
M₂ = molarity of H₂SO₄ solution = 2.50M
V₂ = volume of H₂SO₄ solution = 50mL
On putting all these values on the above equation and calculate for the value of V₁ as:
V₁ = (2.50)(50) / (18) = 6.94mL
Hence correct option is (3) i.e. 6.94mL.
