Question

Mr. Harry's new baby is sick and not nursing well. The doctor suggests Pedialytewhich is a dilute sugar solution along with vitamin C. If there are 25 grams ofdextrose dissolved in 1000 g of solution, what is the percent concentration?

Answer 1

2.5%

Step-by-step explanation

The percentage by mass of a solution can be calculated by dividing the mass of the solute by the mass of the solvent, then, multiplied by 100.

`Percent\text{ }concentration=\frac{Mass\text{ }of\text{ }solute}{Mass\text{ }of\text{ }solution}*100`

According to this question, 25 grams of dextrose is dissolved in 1000 grams of solution. The percent concentration is calculated as follows:

`Percent\text{ }concentration=(25g)/(1000g)*100=2.5\%`

Therefore, If there are 25 grams of dextrose dissolved in 1000 g of solution, the percent concentration is 2.5%
