To find the density of the gas, we can use the formula:

$\text{Density} = \frac{\text{Mass}}{\text{Volume}}$

Given:

• Mass = 1.60 g
• Volume = 1200 mL = 1200 cm³ (since 1 mL = 1 cm³)

Now, substitute the values into the formula:

$\text{Density} = \frac{1.60 \, \text{g}}{1200 \, \text{cm}^3} = 0.00133 \, \text{g/cm}^3$

Thus, the density of the gas is 0.00133 g/cm³.
