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
Answer:
<h3>The answer is 0.622 mL</h3>Explanation:
The volume of a substance when given the density and mass can be found by using the formula
From the question
mass = 12 g
density = 19.30 g/mL
We have
We have the final answer as
<h3>0.622 mL</h3>Hope this helps you

Explanation:
you make use of the formulas
amount(mol) = number of particles ÷ 6.02 × 10^23
and
mass(g) = amount(mol) × molar mass
