Question

If an object has a density of 4.2 g/mL, what is its density in hg/L?

Answer 1

Your answer would be 42 hg/L

Answer 2

I believe "h" stands for hecta-, which means "one hundred."

I will convert from g to hg (divide by 100), then from mL to L (multiply by 1000).

$\frac{4.2g}{mL}*\frac{1hg}{100g}*\frac{1000mL}{1L}=42\frac{hg}{L}$
