Oxygen gas is collected over water. The atmospheric pressure is 748 mmHg, and the temperature of the oxygen is 29 ºC. The pressu
KonstantinChe [14]

The pressure of the oxygen gas collected : 718 mmHg

<h3>Further explanation</h3>

Given

P tot = 748 mmHg

P water vapour = 30 mmHg

Required

P Oxygen

Solution

Dalton's law of partial pressures states that the total pressure of a mixture of gases is equal to the sum of the partial pressures of the component gases

Can be formulated:

P tot = P1 + P2 + P3 ....

The partial pressure is the pressure of each gas in a mixture

P tot = P H₂O + P Oxygen

P Oxygen = 748 mmHg - 30 mmHg

P Oxygen = 718 mmHg

A compound has an empirical formula of SO3 and a molecular mass of 152. What is the molecular formula?
Anettt [7]

Answer:

Molecular formula = S₂O ₆

Explanation:

Given data:

Empirical formula = SO₃

Molecular formula = ?

Molecular mass = 152 g/mol

Solution:

Molecular formula = n (empirical formula)

n = molar mass of compound / empirical formula mass

Empirical formula mass  = 80 g/mol

n = 152 g/mol / 80 g/mol

n = 2

Molecular formula = n (empirical formula)

Molecular formula = 2(SO₃)

Molecular formula = S₂O ₆
