Answer:
Use the formula PV=nRT to get the temperature
Answer: The number of grams of
in 1620 mL is 1.44 g
Explanation:
According to ideal gas equation:

P = pressure of gas = 1 atm (at STP)
V = Volume of gas = 1620 ml = 1.62 L (1L=1000ml)
n = number of moles = ?
R = gas constant =
T =temperature =


Mass of hydrogen =
The number of grams of
in 1620 mL is 1.44 g
Answer:

Explanation:
Hello there!
In this case, given the T-V variation, we understand it is possible to apply the Charles' law as shown below:

Thus, since we are interested in the initial temperature, we can solve for T1, plug in the volumes and use T2 in kelvins:
