Question

7. A piece of wood has a mass of 100 g. If it occupies a volume of 200 cm”, find its density. answer is .5cm ​

Answer 1

Answer:

0.75g/cm³

Step-by-step explanation:

Solution:

(a) Mass of wood = 150g

Volume of wood = 200cm³

Density = m/v

D = 150/200

D - 0.75 g/cm³

Answer 2

Answer:

$\huge \tt \blue{0.5g \: per \: {cm}^{3} }$

Step-by-step explanation:

Given -

Mass of the wood piece (m) = 100 g

Volume of wood piece (V) = 200 cm³

.

To find -

The density of wood

.

Solution -

$\sf \: density = \frac{mass}{volume} \\ = \sf\frac{100 \: g}{200 \: {cm}^{3} } \\ \sf = \frac{1}{2} \frac{g}{ {cm}^{3} }$

= 0.5 g/cm³.

.

Hence the density = 0.5 g/cm³

hope it helps.
