1 g/mL ------------ 8.3454 lbs/gal
1.09 g/mL --------- ?

lbs/gal = 1.09 x 8.3454 / 1

ibs/gal = 9.096 / 1

= 9.096 lbs/gal

The volume occupied by 1.5 mole of gas at 35°C and 2.0 atmosphere of pressure is blank liters

Aneli [31]

Answer: 18.97 L

Explanation:

This can be solved by the Ideal Gas equation:

$P.V=n.R.T$

Where:

$P=2 atm$ is the pressure of the gas

$V$ is the volume of the gas

$n=1.5 mole$ the number of moles of gas

$R=0.0821\frac{L.atm}{mol.K}$ is the gas constant

$T=35\°C+273.15=308.15 K$ is the absolute temperature of the gas in Kelvin

Finding $V$ :

$V=\frac{nRT}{P}$

$V=\frac{(1.5 mole)(0.0821\frac{L.atm}{mol.K})(308.15 K)}{2 atm}$

$V=18.97 L$

Therefore:

The volume occupied by 1.5 mole of gas at 35°C and 2.0 atmosphere of pressure is 18.97 liters

Devices that mix air or oxygen with flammable gasses cannot be used unless approved by

Feliz [49]

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.

During the preparation and usage of flammable gases, safety precautions should be properly enforced such as the wearing of appropriate safety gear and goggles.

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