Question

If the density of an object is 30 g/cm3 and its volume is 10 cm3, what is its mass in grams?
A. 0.33
B. 3
C. 40
D. 300

Answer 1

Hey mate.... .^_^

Here's ur ans. .⬇

Density = Mass/Volume

30 gm/cm^3 = m/10 cm^3

30 gm/cm^3 × 10cm^3 = m

mass = 300 grams.

Answer 2

Hii...☺

Here is your answer.....

__________________________

✴ Density = 30g/cm^3
✴ volume = 10cm^3

⭐ As we know that density of an object is mass per unit volume.

Therefore,

=> 30g/cm^3 = m / 10cm^3
=> m = 300 gm

Hence, mass of the given object = 300gm

✴ Option "D" is the right one...

Hope this helps you...☺
