Question

How many moles are present in 454 grams of co2?

Answer 1

Moles=mass/Mr
mass=454
Mr=12+16+16=44
So,454/44=10.31mol
Answer is:10.31mol

Answer 2

Step-by-step explanation:

Number of moles is defined as mass divided by molar mass.

Mathematically, No. of moles =
`(mass given)/(molar mass)`

Since, it is given that mass present is 454 g and molar mass of
`CO_(2)` is 44.01 g/mol.

Therefore, calculate number of moles as follows.

No. of moles =
`(mass given)/(molar mass)`

=
`(454 g)/(44.01 g/mol)`

= 10.31 mol

Thus, we can conclude that number of moles present in 454 grams of
`CO_(2)` is 10.31 mol.
