Answer:

B.5%

Explanation:

To calculate the percentage concentration you need to use the formula below.

Percentage concentration =(Solute/ Amount Of solution) x 100%

Given:

Pc = ?

Solute = 5g

Solution 5g + 90g = 95g

P.C. (5g/95g) x 100% =

P.C. = 0.05g x 100%

P.C. = 5g

Therefore, the percentage concentration in the following solution: 5g sucrose in 90 grams water is 5%
