Answer:
It's a, trust me I'm very good with chemistry
Explanation:
The partial pressure of an individual gas is equal to the total pressure of the mixture multiplied by the mole fraction of the gas.
Total pressure = 2atm
Mole Fraction = number of moles / total number of moles
Neon
Mole Fraction = 4.46 / 7.35 = 0.607
Partial Pressure = 0.607 * 2 = 1.214 atm
Argon
Mole Fraction = 0.74 / 7.35 = 0.101
Partial Pressure = 0.101 * 2 = 0.202 atm
Xenon
Mole Fraction = 2.15 / 7.35 = 0.293
Partial Pressure = 0.293 * 2 = 0.586 atm
Answer:
B
the humidity is the % of water in the air and it is out of 100% of the air. so 10/100 is low
If 0.25mg of atropine is in 1mL
so
0.50mg of atropine is in x
Answer:
Final temperature of the gas is 576 .
Explanation:
As the amount of gas and pressure of the gas remains constant therefore in accordance with Charles's law:
where and are volume of gas at and temperature (in kelvin scale) respectively.
Here , and
So
849 K = (849-273) = 576
So final temperature of the gas is 576 .
