plz write correct answer

Find volume of gas at STP​

Answer 1

Given :

No. of moles = 8

No. of molecules = 8 × 6.022 × 10²³

Gas = CO2

Note : Volume of 1 mole of gas at STP = 22.4

No. of moles = Given mass / molar mass = Given atom / Na = Given volume / 22 .4

$\frac{8 \times 6.022 \times {10}^{23} }{6.022 \times {10}^{23} } = \frac{volume \: of \: given \: gas}{22.4 \: l}$

Volume of CO2 = 22.4 × 8

= 179.2
