A substance has a mass of 400 grams and a volume of 100 mL. What is the density in [tex]g/mL[/tex]?

A. 0.25
B. 40
C. 40000
D. 4



Answer :

To find the density of a substance, we use the formula for density which is:

[tex]\[ \text{Density} = \frac{\text{Mass}}{\text{Volume}} \][/tex]

Given:
- Mass ([tex]\( m \)[/tex]) = 400 grams
- Volume ([tex]\( V \)[/tex]) = 100 mL

We plug these values into the formula:

[tex]\[ \text{Density} = \frac{400 \text{ g}}{100 \text{ mL}} \][/tex]

Perform the division:

[tex]\[ \text{Density} = 4 \text{ g/mL} \][/tex]

Thus, the density of the substance is [tex]\( 4 \text{ g/mL} \)[/tex].

Out of the given options:
a) 0.25
b) 40
c) 40000
d) 4

The correct answer is:

d) 4
