Answer : The temperature of gas is, 295 K
Explanation :
To calculate the temperature of gas we are using ideal gas equation:
where,
P = Pressure of gas = 1.21 atm
V = Volume of gas = 10.0 L
n = number of moles = 0.500 mole
R = Gas constant =
T = Temperature of gas = ?
Now put all the given values in above equation, we get:
Therefore, the temperature of gas is, 295 K
Answer: 136 g of must be reacted to inflate an air bag to 70.6 L at STP.
Explanation:
Using ideal gas equation:
P= pressure of nitrogen gas = 1 atm (at STP)
V =volume of nitrogen gas = 70.6 L
n = number of moles of nitrogen gas = 1 atm (at STP)
R = gas constant = 0.0821 Latm/Kmol
T = temperature of nitrogen gas = 273 K (at STP)
For the balanced chemical reaction:
3 moles of nitrogen are produced by = 2 moles of
3.14 moles of nitrogen are produced by = moles of
Mass of = Moles × Molar mass = 2.09 mole × 65 g/mol = 136 g
