Question

calculate the mass of sulphur dioxide gas which will contain same number of molecule as present in 4.4g of carbon dioxide

Answer 1

Hey chika ❤

Here's ur answer-

we know that,

$moles \: = \: given \: mass \: \div \: molar \: mass \:$

Given,

Mass of carbon = 4.4

and, molar mass of carbon = 44

So,

$moles \: = \: 4.4 \div 44$
$moles \: = \: 0.1$
Hence,
we have to calculate the mass of 0.1 mole os sulphur dioxide [SO2]

Again,

$moles \: = \: given \: mass \: \div \: molar \: mass$
Moles = 0.1
and, molar mass = 64

$= > 0.1 \: = \: mass \: \div 64$
From above , we can say that

$mass \: of \: moles \: =no.of \: moles \: \times molar \: mass$

$mass \: of \: moles \: = 0.1 \times 64$

$mass \: = \: 6.4$
