An Olympic-size pool is 50.0 m long and 25.0 m wide.
Lostsunrise [7]
1. To calculate the volume of the pool you need to convert the length, width and height into one same unit. The volume would be:
volume= length * width * height
volume= 50m *25m *(48ft *0.3048m)= 18288m^3
volume in gallons= 18288m^3 * (264.172 gallons/m^3)= 483.118 gallons

2. The mass would be found by multiplying density with volume. You will need to some unit conversion to get the mass in kilogram. Remember that 1g= 1000kg and 1m^3= 1,000,000ml
mass= volume * density
mass= 18288m^3 * (10^6 ml^3/m^3) * 1.0 g/mL / (1000g/kg)= 18,288,000 kg

Gaseous C2H4 reacts with O2 according to the following equation:
gavmur [86]
Each mole of C₂H₄ requires 3 moles of O₂ to react.

5.75 moles of C₂H₄ will require:
3 x 5.75 = 17.25 moles

Each mole of gas occupies 22.4 L at STP.
Liters of gas = 17.25 x 22.4
= 3.86 x 10² L

The answer is C.
