Answer:
The answer is
1, 214, 285.71 g/mL
Explanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\ [/tex]
From the question
mass of gas = 8.5 × 10^9 g
But 1 L = 1000 mL
So 7 L = 7000 mL
volume = 7000 mL
So the density of the gas is
[tex]density = \frac{8.5 \times {10}^{9} }{7000} \\ = 1214285.714285...[/tex]
We have the final answer as
1, 214, 285.71 g/mL
Hope this helps you
