How many grams of k2so4 would you need to prepare 1500 g of 5.0% k2so4 solution?
1 answer:
Data Given:
% w/w = 5 %
Solution weight = 1500 g
Solute weight = ?
Formula Used:
% w/w = (Mass of Solute / Mass of Solution) × 100
Solving for Mass of Solute,
Mass of Solute = (% w/w × Mass of Solution) ÷ 100
Mass of Solute = (5 × 1500 g) ÷ 100
Mass of Solute = 75 g K₂SO₄

Answer:
i guess answer is 0.0600
Explanation:
Here,
Density=0.791g/cm^3
Volume=75.89ml
So,
Mass=Density*Volume
=0.791g/cm^3×75.89ml
=60.02g/cm^3.ml
Expressing them in kg
60.02/1000
=0.0600 kg
