Answer to Question #141579 in General Chemistry for yara

Question

What mass of iron (II) sulfate is found in 75mL of 5%w/V solution?

Answer 1

To calculate w/v % concentration:

w/v (%) = mass of solute (g) / volume of solution (mL) × 100

Therefore,

mass of solute (g) = w/v (%) × volume of solution (ml) / 100%

Mass of FeSO₄ = 5% × 75 ml / 100% = 3.75 g

Answer: mass of FeSO₄ is 3.75g
