Question

A piece of steel has volume of 12cmcube and a mass of 96g. what is its density first in g/cmcube? second in kg/mcube?​

Answer 1

As we know from the definition, density is defined as mass per unit volume of any substance.

Now, we know that density has two different units in S. I. and C. G. S. system. In S. I. system, density is measured in Kg/m³ whereas in C. G. S. system, density is measured in g/cm³.

Density = 96/12 = 8 g/cm³ [CGS]

Density = 8 g/cm³ = 8000 kg/m³ [SI]

So, these are the required answers.

Answer 2

Answer:

Explanation:

Here,

Volume of iron, v = 12 cm³

Mass of iron, m = 96 g = 96/1000 kg = 0.096kg

And, we have to find,

Density of iron, d = ?

We know, by formula, that

Putting the values,

Hence, density of Iron is 0.008 kg/m³.

That's your answer.

Hope it'll help.. :-D
