1.	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 = \(\frac{Mass\,of\,CO_2}{Molar\,mass\,of\,CO_2}\) ⇒ Number of moles \(\frac{360g}{44g/mol}\) ⇒ Number of moles = 8.1mol Thus, the number of moles in 360g of the sample is 8.1

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 = \(\frac{Mass\,of\,CO_2}{Molar\,mass\,of\,CO_2}\)

⇒ Number of moles \(\frac{360g}{44g/mol}\)

⇒ Number of moles = 8.1mol

Thus, the number of moles in 360g of the sample is 8.1
