Question

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

Answer 1

1. Maria dissolves:
1kg of salts
3L of water

Bobby dissolves:
2lbs of salt
2pints of water

Which is more concentrated?
1l = 2.11pints
1kg = 2.2 lbs
Maria dissolves
=> 2.2 lbs of salt and 6.33pints of water
While Bobby dissolves
=> 2 lbs of salt with 7pints of water.

Therefore, the more concentrated is Maria’s experiment because she uses more salts than water.
