Scientist A dissolved 1.0 kilogram of salt in 3.0 liters of water. Scientist B dissolved 20 pounds of salt in 7.0 pints of water. Which scentist made a concentrated salt solution? Explain.

scientist A dissolved 1 kg of salt in 3 litres.

scientist B dissolved 20 pounds of slat in 7 pint of water.

we know that 1 pound = 0.543 g

20 pounds=9.07 kg.

1 pint=0.5 litres

so 7 pints = 3.5 litres

so dissoving 1 kg of salt in 3 litres of water and 9.07 kg in 3.5 litres of water

we know that for concentration kg/l units is used.

for A = 1/3=0.33kg/l

and B=9.07/3.5=2.59 kg/l.

so scientist A has prepared more concentrated solution.

Scientist A = 1 kg of salt in 3 litres.

scientist B = 20 pounds of slat in 7 pint of water. 1 pound = 0.543 g. So 20 lbs=9.07 kg. 1 pint=0.5 litres. so 7 pints = 3.5 litresso dissoving 1 kg of salt in 3 litres of water and 9.07 kg in 3.5 litres of waterwe know that for concentration kg/l units is used. for A = 1/3=0.33kg/l and B=9.07/3.5=2.59 kg/l, so scientist A has prepared more concentrated solution.
