Explanation:
March 22, 1868 – December 19, 1953) was an American experimental physicist honored with the Nobel Prize for Physics in 1923 for the measurement of the elementary electric charge and for his work on the photoelectric effect.
P1=836kPa
T1=54.7+273=327.7K
P2=836+79.9=915.9kPa
T2=?
T2=T1*P2/P1
=327.7*915.9/836
=359K=86 degree celsius
Answer: 1 mole Kr
Explanation: solution
83.80g Kr x 1mole Kr / 84 g Kr
= 0.997 or approximately 1 mole Kr
