A popular brand of cola contains 6.50 g of carbon-dioxide dissolved in 1.00 L of soft drink. If the evaporating carbon-di-oxide is trapped in a cylinder at 1.00 atm and 20.0°C,what volume does the gas occupy?

A popular brand of cola contains 6.50 g of carbon-dioxide dissolved in 1.00 L of soft drink. If the evaporating carbon-di-oxide is trapped in a cylinder at 1.00 atm and 20.0°C,what volume does the gas occupy?

Accepted Answer

ক. 3.55x10-3m3

ব্যাখ্যা: কার্বন ডাই-অক্সাইডের মোল সংখ্যা, $n = \frac{W}{M} = \frac{6.50	ext{ g}}{44.01	ext{ g/mol}} \approx 0.1477	ext{ mol}$।
আদর্শ গ্যাস সমীকরণ $PV = nRT$ অনুসারে,
$V = \frac{nRT}{P} = \frac{0.1477 	imes 0.0821 	imes (20 + 273.15)}{1.00} \approx 3.554	ext{ L} = 3.55 	imes 10^{-3}	ext{ m}^3$।
