Answer 1

Answer on Question #40728 – Chemistry – Other

Question:

You have a solution that is $50 \, mg / mL$ of glucose. If you take 0.01 L of this solution how many grams of glucose have you taken.

Answer:

$50 \, mg / mL$ is mass concentration of glucose solution.

$$50 \, mg / mL = 50 \times 1000 \, g / 1000L = 50 \, g / L$$

Density is defined as mass divided by volume:

$$\rho_i = \frac{m_i}{V}$$

Then

$$m = \rho \times V$$

where $\rho_i$ is the mass concentration, $m_i$ is the mass of a constituent, and $V$ is the volume of the mixture.

Mass of glucose is:

$$m = \frac{50 \, g}{L} \times 0.01 \, L = 0.5 \, g$$

Answer: you have taken 0.5 g of glucose.
