To answer this item, we assume that oxygen behaves ideally such that it is able to fulfill the following equation,
PV = nRT
If we are to retain constant the variable n and V.
The percent yield can therefore be solved through the following calculation,
n = (10.5 L)/(22.4 L) x 100%
Simplifying,
n = 46.875%
Answer: 48.87%
Answer:
it will A. d. e. f option above
The first step with any of these problems is putting the mass in grams in terms of moles. How many moles of water are represented by 2.46 g of water? The relationship is the molar mass of water, which is about 18 g/mol. So dimensional analysis shows that 2.46 g water = 2.46 g/18 g = 0.0556 moles of water. That's part a.
The partial pressures of gases in air at 760 mmHg are N₂ (592.8 mmHg), O₂ (159.6 mmHg) and Ar (7.6 mmHg).
<h3>What is partial pressure?</h3>
Partial pressure is the pressure of a gas in a mixture of gases.
Air is a mixture of gases with 78% N₂, 21% O₂, 1% Ar and other gases in trace amounts. The partial pressure of a gas is proportional to its percentage.
Let's calculate the partial pressures of these gases, considering that the atmospheric pressure is 760 mmHg.
pN₂ = 760 mmHg × 78% = 592.8 mmHg
pO₂ = 760 mmHg × 21% = 159.6 mmHg
pAr = 760 mmHg × 1% = 7.6 mmHg
The partial pressures of gases in air at 760 mmHg are N₂ (592.8 mmHg), O₂ (159.6 mmHg) and Ar (7.6 mmHg).
