Question

When 6.4 grams of licl are dissolved in enough water to create a 145-gram solution, what is the solution's concentration, expressed as a percent by mass?

Answer 1

(6.4/145)(100)=4.41379% LiCl 

Answer 2

The mass percentage of the lithium chloride solution is 4.41%.

Step-by-step explanation:

Mass of lithium chloride = 6.4 g

Mass of the solution = 145 g

`Mass\%=\frac{\text{mass of the compound}}{\text{mass of the solution}}* 100`

`Mass\%=(6.4 g)/(145 g)* 100=4.41\%`

The mass percentage of the lithium chloride solution is 4.41%.
