🤓 Based on our data, we think this question is relevant for Professor McCarty's class at NCSU.

Glucose makes up about 0.10% by mass of human blood.

Calculate this concentration in ppm.

We are asked to calculate the concentration of 0.10% glucose in human blood in ppm.

When transforming one unit to another, recall the conversion factors and/or constants that will be used in the calculation.

**Given:**

0.10% glucose → ppm glucose

Recall the formula for mass %:

$\overline{){\mathbf{mass}}{\mathbf{\%}}{\mathbf{=}}\frac{\mathbf{mass}\mathbf{}\mathbf{component}}{\mathbf{Total}\mathbf{}\mathbf{mass}}{\mathbf{\times}}{\mathbf{}}{\mathbf{100}}}$

Recall also that:

$\overline{){\mathbf{1}}{\mathbf{}}{\mathbf{ppm}}{\mathbf{}}{\mathbf{=}}{\mathbf{}}\frac{\mathbf{1}\mathbf{}\mathbf{mg}\mathbf{}\mathbf{solute}}{\mathbf{1}\mathbf{}\mathbf{kg}\mathbf{}\mathbf{solution}}}$
