D. 8.95 Gg/L to g/mL

Answer 1

Gg would be the abbreviation of gigagram.

Since "giga" means a billion, 1 Gg is very large so there are 1,000,000,000 grams in 1 Gg

mL is the abbreviation for milliliter.

Since "milli" means 1/1000, then a mL is very small so there are 1000 mL in 1 liter

So set up the ratios above so that "Gg" on top will cancel "Gg" on the bottom, and "L" on the bottom will cancel with "L" on the top like this:

Then multiply the top numbers together and divide by the bottom numbers. 8.95 • 1,000,000,000 • 1 divided by (1 • 1 • 1000) or 8,950,000,000/1000 = 8.950,000 g/mL
