2.565L
Explanation:
- Charles law states that the volume of an ideal gas at constant pressure is directly proportional to the absolute temperature.V/T=K
V1/T1=V2/T2
Unit of Kelvin = 273.15
- To get the absolute temperature, we need to convert the degree celsius temperature to kelvin.
T1= 22+273.15= 295.15 K
T2 = 71+273.15= 344.15 K
V1 = 2.20 L
V2 =?
2.20/295.15=V2/344.15
0.00745 x 344.15 = 2.565 L
Hence, 2.565 L is the new volume of the balloon.
-0° freezing point ice or ice cream
Answer:
32
Explanation:
The vapour density of a gas is the number of times a given volume of gas or vapour is as heavy as the same volume of hydrogen at a particular temperature and pressure.
Vapour density = 2 × relative molecular mass of the gas or vapour
Relative molecular mass of SO2 = 32 + 2(16) = 64
Hence;
Vapour density of SO2 = 64/2
Vapour density of SO2 = 32
