answer...............

Answer 2

Answer:

Explanation:

The equation for the above reaction is as follows:

(graphite is an allotrope of carbon--C)

C + O2 -------» CO2

Therefore 1 mole of graphite requires 1 Mole of O2 to give 1 mole of CO2.

Calculate the moles of graphite:

Molar mass of C = 12

Mass = 2400 g

moles = mass/molar mass

= 2400/12

=200 moles

If 1 mole of C requires 1 mole of O2

then 200 moles requires  = 1 x 200 / 1

                                         = 200 moles

  

            Find mass of oxygen: (molar mass of O2= 32, moles=200)

mass = moles x molar mass

         = 200 x 32

         = 6400g

          = 6.4kg of oxygen

Find the volume of oxygen:

Ideal gas law..... states that 1 mole of an ideal gas occupies 22.4 litres.

                       

 Therefore,

200 moles of O2 occupies= (22.4 x 200) liters

=4480 liters

Therefore, volume of oxygen is 4480 liters.

Hope it helps you dear!!!
