Answer:
59K
Step-by-step explanation:
Using the general gas law equation:
PV = nRT
Where;
P = pressure (atm)
V = volume (L)
n = number of moles (mol)
R = gas constant (0.0821 Latm/molK)
T = temperature (K)
According to the information given in the question;
- mass of hydrogen gas = 20.2g
mole = mass/molar mass
mole = 20.2/2.015
mole = 10.01mol
- Pressure = 110 Kpa
1 kilopascal = 0.00987 atmosphere
110kPa = 110 × 0.00987
= 1.09atm
- Volume = 4.45 x 10^-2 kL
1 kL = 1000L
4.45 x 10^-2 kL = 4.45 x 10^-2 × 10³
4.45 × 10¹
= 44.5L
Using PV = nRT
T = PV/nR
T = 1.09 × 44.5/0.0821 × 10.01
T = 48.505/0.821
T = 59.02
T = 59K
