Question

What is the mass of 2.2 ml of a substance with a density of 1.59 g/mL?

Answer 1

density = mass/volume

rearranging to solve for mass would yield:

mass = density x volume

Answer 2

Is 2.2 the Volume?

Answer 3

A. 3.5 g

B. 3.5 mL

C. 3.5 g/mL

D. 3.5

are my choices.....

Answer 4

mL are a unit of measurement that specify the volume of a solution. So if we look at it this way:

2.2 mL x 1.59g/mL = 3.498, or 3.5g

The mL cancel each other out, leaving you with just grams, which is the mass. A little more in depth you can see just the units here:

mL can be rewritten as mL/1 because anything divided by 1 is itself. So, if we multiply the fractions like so:

mL/1 x g/mL you can see that the mL cancel each other out (anything divided by itself is 1) leaving you with just grams. Hope this helps!

Answer 5

The answer is A, if you didn't know already
