Question

no. of gram atom in 5 moles of co2​

Answer 1

Answer

1 mole of CO2 has moles of Oxygen atoms =2

then 5 moles will have no of moles or no of gram atoms of Oxygen=2×5=10 moles or 10×16=160g

1 mole of CO2 has moles of C atom=1

then 5 moles will have no of moles or no of gram atoms =1×5=5moles or 5×12=60g

Explanation:

Gram atom( for Element)

The atomic mass of an element expressed in grams is called one gram atom or one gram mole or simply a mole of that element

It is given by

Number of gram atoms or moles of an elements =Mass of elements in grams

                                                                               Atomic mass of an element

I think my my answer will be helpful

Answer 2

Answer:

2.51× 10^23 atoms of carbon

Explanation:

Carbon's mass = 5 g

Carbon's Molar mass = 12g/mol

Number of moles = 5g/12 g mol-1 = 0.417 moles

1 mole of carbon contains 6.022×10^23 atoms

By unitary method,

0.417 moles of carbon contains= 0.417×6.022×10^23 atoms = 2.51× 10^23 atoms of carbon
