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?

Respuesta :

mergl
(6.4/145)(100)=4.41379% LiCl 

Answer:

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

Explanation:

Mass of lithium chloride = 6.4 g

Mass of the solution = 145 g

[tex]Mass\%=\frac{\text{mass of the compound}}{\text{mass of the solution}}\times 100[/tex]

[tex]Mass\%=\frac{6.4 g}{145 g}\times 100=4.41\%[/tex]

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