Question

Calculate number of moles in 1.1g co2

Answer 1

Since the Molecular weight of CO2 is 44.

Therefore,

Number of moles = Weight /Molecular weight

Therefore,

moles = 1.1/44

=0.025

Since no. of particles = Moles × Avagadros number

Therefore,

Number of Particles = 0.025 × 6.022×10^23

= 0.151 × 10^23 molecules

Answer 2

1 mole of CO2 weighs 44 g

so x mole = 1.1g

By cross multiplying... 0.025 moles ll b d ans .... follow me plz..
