Question

For a science experiment, Marcia dissolved 1.0 kilogram of salt in 3.0 liters of water. For a different A experiment, Bobby dissolved 2.0 pounds of salt in 7.0 pints of water. Which person made a more concentrated salt solution? Explain. Use 1 L= 2.11 pints. Round your answer to the nearest hundredth.

If you could explain the steps I would appreciate it a lot.

Answer 1

For Marcia, she has 1 kg salt/3 liters H2O = .33 kg salt/liter H2O

For Bobby, he has 2 lbs salt/7 pints H2O x 2.11 pints/1 liter x 1 kg/2.205 lbs = .27 kg salt/liter H2O

Marcia has the higher concentration!
