Question

5 g of glucose is dissolved in 95g of water. What is the mass percentage of glucose

Answer 1

Mass percentage=
$\frac{mass \: of \: solute(glucose)}{mass \: of \: solution(water + glucose)} \times 100$
Mass percentage=
$\frac{5g}{95g + 5g}\times 100 = \frac{5g}{100g}\times 100 = 5\%$

Answer 2

Answer: The Mass percentage of glucose is 5%.

Explanation: The mass of solute or glucose $= 5g.$

                      The mass of solvent or water   $= 95g.$

                       The mass of the solution           $= 100g.$  

                     The mass percentage of glucose$= \frac{mass of solute or glucose}{mass of solution}$×$100.$

                                                                             $= \frac{5}{100}$ ×$100.$

                                                                             $= 5%$%.

Hence, the final answer for a mass percentage of glucose is five percent.
