Answer:

The answer is "0.00172172603".

Explanation:

Given:

$Mass (M) = 1.60 \times 10^{-3} \ g\\\\Density (D) = 9.293 \times 10^{-1} \ \frac{g}{cm^3}\\\\Volume (V) = ?$

Formula:

$\to \bold{V = \frac{M}{D}}$

$= \frac{1.60 \times 10^{-3}}{9.293 \times 10^{-1}} \\\\ = \frac{1.60 \times 10^{1}}{9.293 \times 10^{3}} \\\\ = \frac{1.60 \times 10}{9.293 \times 1000} \\\\ = \frac{1.60 }{9.293 \times 100} \\\\ = \frac{1.60 }{929.3 } \\\\= 0.00172172603$

Flammable gases are gases that have the tendency to explode (burst into flames) when they come in contact with the appropriate quantities of air, oxygen, or any suitable oxidant.

Devices that mix air or oxygen with flammable gasses cannot be used unless approved by an authorized or approved personnel.

Examples of flammable gases are hydrocarbons such as Propane, Acetylene, e.t.c.

Flammable gases are dangerous to humans and the environment and if they are not handled properly, can cause severe damages and even death.
