Question

how many litres are present in 52g of co2 at stp

Answer 1

Given mass of CO2 = 52Grams

Molar mass of CO2 = 44 Grams

where:-

Mass of Carbon =12g

mass of oxygen =16 g

$\rule{200}{2}$

we know :-

$Number\:of\:moles=\dfrac{given\:mass}{molar\:mass}$

Number of moles of CO2 given will be :-

$=\dfrac{52}{44}\\ \\ \\=\dfrac{13}{11}moles$

$\rule{200}{2}$

we also know :-

$moles=\dfrac{volume\:given}{22.4}$

Hence

$Given\:Volume=moles*22.4$

Thus,

Volume of CO2 given at STP will be :-

$=\dfrac{13}{11}*22.4\\ \\ \\=26.4727\\ \\ \\ \approx{26.473L}$

Answer 2

$\huge\fcolorbox{pink}{Red}{ ★A᭄ΠSWΣR✍︎}$

Given mass of CO2 = 52Grams

Molar mass of CO2 = 44 Grams

where:-

Mass of Carbon =12g

mass of oxygen =16 g

Moles of CO^2

= 44/4.4

=0.1

Volume of 1 mole = 22.4 L

Volume of 0.1 mole = 2.24 L
