Answer: The molar mass of the gas is 31.6 g/mol
Explanation:
According to ideal gas equation:
P = pressure of gas = 3.0 atm
V = Volume of gas = 25.0 L
n = number of moles = ?
R = gas constant =
T =temperature =
Moles =
The molar mass of the gas is 31.6 g/mol
Answer:1) Volume of required is 55.98 mL.
2) 0.62577 grams of is produced.
Explanation:
1) Molarity of
Volume of
Molarity of
Volume of
According to reaction, 1 mole of reacts with 3 mole of
, then, 0.0041985 moles of
will react with:
moles of
that is 0.0125955 moles.
Volume of required is 55.98 mL.
2)
Number of moles of
According to reaction, 3 moles of gives 1 mole of
, then 0.004485 moles of
will give:
moles of
that is 0.001495 moles.
Mass of =
Moles of × Molar Mass of
= 0.001495 moles × 418.58 g/mol = 0.62577 g
0.62577 grams of is produced.
