Calculate the volume of liquid in the round flask sketched below. give your answer in liters, and round to the nearest 0.01l .

Hey There!

Assuming the part of the round flask containing liquid to be perfect sphere, we can calculate it's volume.

Given diameter of sphere = 24 cm  

Therefore radius of the sphere, r= 24/2= 12 cm

Volume of the sphere of diameter 24 cm = (4/3)*pi*r³ = 7,238.23 cm3

Conversion of cm³ to L

1 L= 1 dm³

1 dm = 10 cm

Therefore 1L= 1 dm³ = 1000 cm³

So the volume of liquid in the round flask = 7.24 L( round of to nearest 0.01 L)

the ideal gas law equation is as follows

pv = nrt

where p - pressure

v - volume

n - number of moles

r - universal gas constant

t - temperature

so if the pressure, volume and temperature are already known

we are left with n and r

since r is the universal gas constant that has a known fixed value then r too is known

so we are left with 'n'

once we know temperature volume and pressure

we can find the number of moles of gas present using the ideal gas law equation
