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

Sagot :

Answer:

[tex]d=1.78\times 10^{-7}\ Dg/\mu m^3[/tex]

Explanation:

Given,

The density of Helium is [tex]1.78\times 10^4\ g/cm^3[/tex]

We need to find the density in Dg/μm

We know that,

1 g = 10 dg

1 cm³ = 10¹² μm³

So,

[tex]d=1.78 \times 10^4\ g/cm^3\\\\=1.78 \times 10^4\times \dfrac{10\ dg}{10^{12}\ \mu m^3}\\\\=1.78\times 10^{-7}\ Dg/\mu m^3[/tex]

So, the density of Helium is equal to [tex]1.78\times 10^{-7}\ Dg/\mu m^3[/tex].
