Calculate the number of moles in 360 g of this gas sample.
[Given, atomic masses of C = 12 u, O = 16 u, NA = 6.022 × 1023 per mole]
Answer :
Given:
Mass of gas = 360g
Molar mass = 44g/mol
To calculate the number of moles, we apply the formula:
⇒
⇒ Number of moles = 8.1mol
Thus, the number of moles in 360g of the sample is 8.1
