Answer : The concentration of is, 0.12 M
Explanation :
Using Henry's law :
where,
= concentration of
= ?
= partial pressure of
= 4.5 atm
= Henry's law constant =
Now put all the given values in the above formula, we get:
Thus, the concentration of is, 0.12 M
Answer : The amount of oxygen gas collected are, 0.217 mol
Explanation :
Using ideal gas equation :
where,
P = pressure of gas = (1 atm = 760 torr)
V = volume of gas = 5 L
T = temperature of gas =
n = number of moles of gas = ?
R = gas constant = 0.0821 L.atm/mol.K
Now put all the given values in the ideal gas equation, we get:
Thus, the amount of oxygen gas collected are, 0.217 mol
