Question

The density of lead (Pb) is 11.34 g/cm3. Find the density of Pb in kg/dm3.

Answer 1

Answer:
`11.34 kg/dm^3`

Explanation:

Given : The density of lead (Pb) is
`11.34 g/cm^3`

We know that 1 kg = 1000 gm

⇒ 1 gm =
`(1)/(1000)\ kg`

1 dm = 10 cm

Also, 1 cm =
`(1)/(10)\ dm`

Then the density of Pb =
`11.34*(10*10*10)/(1000)`

Then the density of Pb =
`11.34 kg/dm^3`

Answer 2

`11.34(kg)/(dm^3)`

Explanation:

we know that

The density of lead (Pb) is
`11.34(g)/(cm^3)`

Remember that

1 kg=1,000 g ------> 1 g=1/1,000 kg

1 dm=10 cm -------> 1 cm=1/10 dm

substitute

`11.34((1/1,000))/((1/10)^3)(kg)/(dm^3)`

`11.34((1/1,000))/((1/1,000))(kg)/(dm^3)`

Simplify

`11.34(kg)/(dm^3)`
