Interpretation:

The grams of KBr that are contained in 125g of a 6.25%

KBr solution is to be calculated.

Concept Introduction:

Solution may be defined as the mixture of a minor component which is known as solute and the major component that is known as solvent. The solute is uniformly distributed in the solvent.

Mass percentage is defined as the total mass of solute divided by the total mass of the solution, multiplied by 100 to get the percentage. The formula for the same is,

Mass%=massofsolutegmassofthesolutiong×100.

Explanation

The given mass percent of KBr solution is 6.25%.

The given grams of KBr solution is 125g.

The formula for the calculation of mass percentage is:

Mass%=massofsolutegmassofthesolutiong×100

The expression to calculate the mass of the solute, KBr, is,
