For a science experiment marcia dissolved 1.0 kilogram of salt in 3.0 liters of water. for a different experiment, bobby dissolved 2.0 pounds of salt in 11.0 pints of water. which person made a more concentrated salt solution? complete the explanation. use 1 kg = 2.2 lb and 1 l = 2.11 pints. round your answers to the nearest hundredth.

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.
