Question

1. convert the following: a. 15 cm³ to liters b. 7.38 g to kilograms c. 6.7 s to milliseconds d. 94.5 g to micrograms

Explanation:

Step1: Recall volume conversion factor

We know that $1\ cm^{3}=1\ mL$ and $1\ L = 1000\ mL$. So for part a, $15\ cm^{3}=15\ mL$. Then, $15\ mL=\frac{15}{1000}L = 0.015\ L$.

Step2: Recall mass - mass conversion factor

For part b, since $1\ kg=1000\ g$, then $7.38\ g=\frac{7.38}{1000}kg=0.00738\ kg$.

Step3: Recall time - time conversion factor

For part c, as $1\ s = 1000\ ms$, so $6.7\ s=6.7\times1000\ ms = 6700\ ms$.

Step4: Recall mass - mass conversion factor

For part d, because $1\ g = 1000000\ \mu g$, then $94.5\ g=94.5\times1000000\ \mu g=94500000\ \mu g$.

Answer:

a. $0.015\ L$
b. $0.00738\ kg$
c. $6700\ ms$
d. $94500000\ \mu g$
