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.
