Question

what will be the mass percentage of a solution containing 30 gram of common salt in 220 gram of water​

Answer 1

Answer:

12

Explanation:

formula pf concentration of the solution is-solute/solution*100

30/250*100

Answer 2

Answer: The mass percent of solution is 12 %.

Explanation:

To calculate the mass percent of element in a given compound, we use the formula:

$\text{Mass percent of solution}=\frac{\text{Mass of solute}}{\text{mass of solute +mass of solvent}}\times 100$

Mass of solute = 30 g

Mass of solvent = 220 g

Putting values in above equation, we get:

$\text{Mass percent of solution}}=\frac{30}{30+220}\times 100=12\%$

Hence, the mass percent of solution is 12 %.
