Question

Plzzzz telll me the answer only brilliant girls
Plzzz solve question number 22


I mark brilliant answer

Answer 1

HERE IS UR ANS :-

Atomic mass of carbon=12u

oxygen=16u

molecular mass of CO2=12+2x16=12+32=44u

molar mass = 44g 

1mole of CO2 contains 44g

3 moles of CO2 ---?

=3x44/1=132g

Molar mass of NH3=14+3x1=17g

Formula : Number of moles= Given weight/molar mass

=132/17

=7.76 moles

 ∴Number of moles of ammonia that have the same mass as that of 3 moles of carbon dioxide is7.76 mol 

HOPE THIS MAY HELP U ^-^

Answer 2

it is given that what will be the mass of carbon will be the mass of ammonia

we know that
no.of moles=mass given/molar mass

so molar mass of co2 is 12+2×16
=12+32
=44

3=mass given/44
mass given=44×3
=132g

since co2 =Nh3=132g
molar mass of nh3 = 14+3×1=17
no.of moles=132/17
no of moles=7.76moles
