A solution contains 45g/100 mL of glucose. It is diluted 1/10 and diluted a second time 1/10. What is the concentration in g/100 mL of the final solution?
A) 45.0 g/100mL
B) 4.50 g/100 mL
C) 0.45 g/100mL
D) 0.045 g/100mL

Question

Quizplus · Accepted Answer

The concentration of the solution is reduced by a factor of 10 each time it is diluted. Therefore, the final concentration is 45 g/100 mL / 10 / 10 = 4.5 g/100 mL.
