A6.35 l sample of carbon monoxide is collected at 55.0◦c and 0.892 atm. what volume will the gas occupy at 1.05 atm and 59.0◦c? 1. 1.96 l 2. 6.68 l 3. 5.46 l 4. 6.10 l 5. 4.82 l

option 3. 5.46 L

Explanation:

1) Data

2) Chemical principle

3) Solution

a) Conversion of units

The ideal gas law is valid for temperature in absolute units (Kelvin); hence, you have to converte °C to K.

b) Clear V₂ from the combined law of gases

c) Substitute values and compute

The answer must be reported with three significant figures, which is the number used for the data.

the gas will ocupy 5.46 liter at the new condictions of pressure and temperature.

pure substance: iron,copper

impure substance: water,charcoal
