Answer:
As per the given statement:
Using ideal gas law equation:
where
P represents the Pressure of a gas
V represents the Volume it occupies
R represents the Universal constant , usually given as:
R = 0.082 atm L/ mol k
First convert Celsius into Kelvin.
T = 273 + 30 = 303 K
Use conversion:
1 L = 1000 mL
V = 74.5 mL = 
L
Now substitute the given values we have;
Simplify:
n = 0.00279757305
or
n ≈0.0028 moles.
Since carbon monoxide, CO has molar mass of 28.01 g/mol
then;
g
Therefore, 0.078 g of CO(g) are there in 74.5 mL of the gas at 0.933 atm and 30 degree C

Nuclear energy is harmful because it releases of harmful ionizing radiation and has been employed in the production of atomic bombs and hydrogen bombs.
Nuclear energy is beneficial in that it produces vast amount of energy for domestic and industrial purposes.
<h3>What is nuclear energy?</h3>
Nuclear energy refers to the energy which is produced as a result of the changes that occur in the nucleus of atoms of elements.
Nuclear energy produces the largest amount of energy when compared to other forms of energy sources.
Nuclear energy is produced by two types of nuclear reactions:
- Nuclear fission and Nuclear fusion
Nuclear energy is harmful in that it results in the release of harmful ionizing radiation which damages cells and tissues of living organisms.
Nuclear energy is also harmful because nuclear energy has been employed in the production of atomic bombs and hydrogen bombs.
On the other hand, nuclear energy is beneficial in that it produces vast amount of energy which can be used for domestic and industrial purposes. It also produces fewer wastes that damage the environment compared to fossil fuels.
In conclusion, nuclear energy is both beneficial and harmful.
