Explanation:
Density is m/V. Also, 1 liter = 1000 [tex]cm^3[/tex]. So, we get 0.890/(5*1000) = [tex]1.78*10^{-4}[/tex] g/cm^3. You can convert this to kg/m^3 as well by multiplying it by 10. Depends which one you want.
The ratio of the mass in grams and volume in cubic meters gives the density. The density of 0.80 gm helium is 1.78 × 10 ⁻⁴ g/cm³.
What is density?
Density is the amount or the number of entities that can be contained in an area. It is denoted by ρ and is calculated as,
Given,
Mass = 0.890 gm
Volume = 5000 cm³
ρ = Mass ÷ Volume
= 0.890 ÷ 5000
= 1.78 × 10 ⁻⁴ g/cm³
Therefore, 1.78 × 10 ⁻⁴ g/cm³ is the density of helium.
