A sample of oxygen gas has a volume of 3.24 L at 29°C. What volume will it occupy at 104°C if the pressure and number of mol are

ohaa [14]

<u>Answer:</u> The final volume of the oxygen gas is 4.04 L

<u>Explanation:</u>

To calculate the final temperature of the system, we use the equation given by Charles' Law. This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure and number of moles.

Mathematically,

$\frac{V_1}{T_1}=\frac{V_2}{T_2}$

where,

$V_1\text{ and }T_1$ are the initial volume and temperature of the gas.

$V_2\text{ and }T_2$ are the final volume and temperature of the gas.

We are given:

$V_1=3.24L\\T_1=29^oC=(29+273)K=302K\\V_2=?\\T_2=104^oC=(104+273)K=377K$

Putting values in above equation, we get:

$\frac{3.24L}{302K}=\frac{V_2}{377K}\\\\V_2=4.04L$

Hence, the final volume of the oxygen gas is 4.04 L

Genetic information is encoded in a molecule called DNA?

grandymaker [24]

True

Explanation:

The DNA is the structure in living organisms that encodes genetic information.

DNA = DeoxyriboNucleic Acid.

The DNA is made up of a double helix structure of two strands.
It is made up of a phosphate group,deoxyribose sugar and four nitrogenous bases.
The DNA is contained in the nucleus of every cell.
Crick and Watson suggested the molecular structure of the DNA to be a double helix shape.
