Question

A sample of an unknown liquid has a volume of 30.0 mL and a mass of 6 g. What is its density? Show your work or explain how you determined this value.

Answer 1

Density of liquid having a volume of 30.0 mL and a mass of 6 g is

`0.2 (g)/(ml)`

Step-by-step explanation:

Density of a substance is given by mass divided by volume

Mathematically it can be represented as

`D = (M)/(V)`

Where D represents the density

M represents the mass and

V represents the volume

Substituting the given values in above equation we get -

`D = (6)/(30) \\= 0.2(g)/(ml) \\= 200 (Kg)/(m^3)`

Hence, density of liquid having a volume of 30.0 mL and a mass of 6 g is

`0.2 (g)/(ml)`

Answer 2

Alright, so the formula for density is d=m/v or in words, density is equal to the mass divided by the volume. Since grams (g) is a unit of mass, you will place that at the top of your fraction, and since mL is a unit of volume, it will be placed at the bottom. Your equation will look like D=6/30.0 mL When you answer the question, your unit will be g/mL. Hope this helps!
