Question

How many moles are in 216.6 g of dinitrogen oxid (N20)

Answer 1

4.92

Step-by-step explanation:

Answer 2

`\qquad \quad \large {\pmb{ \frak { \mid {\overline{ \underline{\purple{ \bigstar \: Required \: Answer \: \bigstar}}}}}} \mid}\\`

We are given –

Mass of
`\bf N_2O` is 216.6 g and we are asked to find number of moles present in 216. 6 g of
`\bf N_2O`

`\qquad`
`\pink{\bf\longrightarrow { Molar \:mass \:of \: N_2O:-} }`

`\qquad`
`\bf \twoheadrightarrow 14* 2+ 16`

`\qquad`
`\bf \twoheadrightarrow 44`

`\qquad`____________________

Calculating the number of moles present in 216.6 g of
`\bf N_2O`

`\qquad`
`\purple{\sf\longrightarrow { No \:of \:moles = (Given \:mass)/(Molar\: mass)}}`

`\qquad`
`\bf \twoheadrightarrow (216.6)/(44)`

`\qquad`
`\bf \twoheadrightarrow \cancel{(216.6)/(44)}`

`\qquad`
`\bf \twoheadrightarrow 4.9\: moles`
