If 31.8 grams of licl are dissolved in 225 grams of water, what is the concentration of the solution in percent by mass?

12.4 %

Explanation:

To calculate the mass percent of solution, we use the formula:

Given :

mass of solute (LiCl) = 31.8 grams

mass of solvent (water) = 225 grams

Mass of solution = mass of solute + mass of solvent = 31.8 g + 225 g= 256.8 g

Thus concentration of the solution in percent by mass is 12.4%

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.

i'm wiling to try and you : )
