Question

a piece of steel has a volume 12cm3 and a mass of 96g.(a) g/km3 (b) kg/m3.

Answer 1

Answer:

Explanation:

Given :-

Volume of steel piece, V = 12³ cm = 12 × 10⁻⁶

Mass of steel piece, m = 96 g = 96 × 10⁻³

To Find :-

Density  of steel piece = ?

Formula to be used :-

Density, D = Mass/Volume

Solution :-

Density = Mass/Volume

Density = 96 × 10⁻³ / 12 × 10⁻⁶

Density  = 8 × 10³ kg/m³

Hence, the density  of steel piece is 8 × 10³ kg/m³

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
