Answer: The density of gas is [tex]1.43\times 10^{-3}g/cm^3[/tex]
Explanation:
We are given:
Mass of empty balloon, [tex]m_1[/tex] = 2.42 g
Mass of balloon with gas, [tex]m_2[/tex] = 10.24 g
Mass of gas = [tex]m_2-m_1=10.24-2.42=7.82g[/tex]
To calculate density of a substance, we use the equation:
[tex]\text{Density of a substance}=\frac{\text{Mass of a substance}}{\text{Volume of a substance}}[/tex]
We are given:
Mass of gas = 7.82 g
Volume of gas = [tex]5470cm^3[/tex]
Putting values in above equation, we get:
[tex]\text{Density of gas}=\frac{7.82g}{5470cm^3}\\\\\text{Density of gas}=1.43\times 10^{-3}g/cm^3[/tex]
Hence, the density of gas is [tex]1.43\times 10^{-3}g/cm^3[/tex]
