ok off topic but are you in k12 loll
Explanation:
The number of moles of oxygen in the gas is 1.5 L.
The correct option is (A).
<h3>What are moles? </h3>
The mole is the International System of Units' foundation unit of material quantity.
Given,
The volume of gas is 33.6 L
Pressure is 1 atm.
Temperature is 0°C
Molar gas volume is 22.4 L
There is no temperature and pressure is 1 atm.
By formula of moles, volume is divided by molar mass

Thus, option A is correct. 1.5 L.

The density of the carbon tetrachloride is 1.59 g/mL.
Mass of CCl₄ = 703.55 g – 345.8 g = 357.75 g
Density = mass/volume = 357.75 g/225 mL = 1.59 g/mL
If 4 moles of P is used by 5 mole of O2
then....0.489 moles will be used by 5/4 × .489 = .611 moles of O2
so .611 moles
so if 4 moles of P is burnt , 1 mole of P4O10 is produced ....so for .489 moles...... .489/4=.122 moles !
so mass will be .122× 283.89 = 34.7 grams
so first ans is .611 moles and second is 34.7 grams !
if you have any problem regarding this , just comment !!!
