Question

What is the mass in mg of a 2.275mL sample, if it has a density of 3.75kg/L ?

Answer 1

Density=mass/volume
to convert 1 kilogram 1 000 000 milligrams
A milligram is a unit of mass in the Metric System. The symbol for milligram is mg. There are 1,000 milligrams in a gram.
What is a kilogram (kg)?
A kilogram is a unit of mass in the Metric System. The symbol for kilogram is kg. There are 1,000 grams in a kilogram.
Change 2.275 ml to L
1 ml =0.001 L
2.275=x L
x=0.00275 L
x/0.00275=3.75*10^6

Answer 2

x in the last equation represent the mass

Answer 3

I don't think that's correct. The answer from what you supplied is 10312.5 and that's not correct according to the website it was entered on.

Answer 4

mass=volume*density
you just regulate these units.

Answer 5

@Abmon98 was correct but made a small typo. The volume is 0.002275 mL, not 0.00275.

Answer 6

(2.275mL) x (3.75 x 10^3 mg/mL) = 8531 mg
