उत्तर
P1 = 750 mm P2 = 760mm
V1 = 44 lit. V2 = ?
T1 = 298K T2 = 273K
`("P"_1"V"_1)/"T"_1 = ("P"_2"V"_2)/"T"_2`
V2 = `("P"_1"V"_1"T"_2)/("T"_1"P"_2)`
= `(750 xx 44 xx 273)/(298 xx 760)`
∴ V2 = 39.78 lit.
22.4 lit. of CO2 at STP has mass = 44 g
∴ 39.78 lit. of CO2 at STP has mass = `(44 xx 39.78)/22.4`
= 78.14 g
