For a science experiment marcia dissolved 1.0 kilograms of salt in 3.0 liters of water for a different experiment bobby dissolved 2.0 pounds of salt in 7.0 pints of water which person made a more concentrated salt solution explain use1l=2.11pints

Marcia dissolved 1 kg of salt in 3 litres of water.
Bobby dissolves 2 pounds of salt in 7 pints of water
2.11 pints = 1 litre
7 pints = 7/2.11
           = 3.32 litre
1 pound =0.45 kg
2 pound = o.45*2 kg
               = 0.9 kg
So we find that Bobby is dissolving 0.9kg of salt in 3.32 litre of water
Marcia is dissolving 1 kg of salt in 3 litres of water.
So it can be said that Marcia made a more concentrated salt solution.

What is the question ehre
