Question

2. The density of helium is 1.78 X 104 g/cm. What is this
density in Dg/um??

Answer 1

`d=1.78* 10^(-7)\ Dg/\mu m^3`

Step-by-step explanation:

Given,

The density of Helium is
`1.78* 10^4\ g/cm^3`

We need to find the density in Dg/μm

We know that,

1 g = 10 dg

1 cm³ = 10¹² μm³

So,

`d=1.78 * 10^4\ g/cm^3\\\\=1.78 * 10^4* (10\ dg)/(10^(12)\ \mu m^3)\\\\=1.78* 10^(-7)\ Dg/\mu m^3`

So, the density of Helium is equal to
`1.78* 10^(-7)\ Dg/\mu m^3`.
