Question

5. What is the density of 4.5 mL of a liquid that has a mass of 1.3 grams?
a. 0.289 g/mL
c. 3.20 g/mL
b. 3.46 g/mL
d. 0.468 g/mL

Answer 1

Answer:

A. 0.289g/mL

Explanation:

Using the equation for density which is d = m/v  or density = mass/volume, we input 1.3g/4.5mL and get 0.289g/mL.

Answer 2

Answer:

Option(a)

The density of 4.5 mL of a liquid that has a mass of 1.3 grams is 0.289g/ml

Explanation:

We know that density is given by mass upon volume i.e,

$\text { density }=\frac{\text { mass }}{\text { volume }}$

we are given volume of the liquid = 4.5mL

and mass of the liquid = 1.3 grams

So, by substituting the given values in the formula we obtain the density of liquid as

$\text { density }=\frac{\text { mass }}{\text { volume }}$

$\text { density }=\frac{1.3}{4.5}$

= 0.28888..

= approx 0.289 g/mL which is the density of the liquid
