Question #9b6bc

Answer 1

The `"mass"/"mass"` "`%"` concentration of a solution is calculated by dividing the mass of solute by the mass of solution then multiplying times 100%.

`"mass"/"mass"` `"%"` = `"mass of solute"/"mass of solution"` x `"100%"`

Given:
mass of solute (`"SrCl"_2`) = 6.50 g
mass of solution = 250.0 g

Unknown:
% concentration

Solution:

`"mass"/"mass"` % = `"6.50 g SrCl"_2"/"250.0"` `"g"` `"solution"` x `"100%"` = `"2.6%"`

Answer:
The mass/mass % concentration of the solution is 2.6%.
