How do you find the average molar mass of a gas?
Knowing the molar mass of an element or compound can help us stoichiometrically balance a reaction equation. The average molar mass of a mixture of gases is equal to the sum of the mole fractions of each gas (xi) multiplied by the molar mass (Mi) of that particular gas: ¯M=∑ixiMi M ¯ = ∑ i x i M i .
What is the molar mass of o2?
15.999 uOxygen / Atomic mass
How do you calculate average moles?
- First you must calculate the number of moles in this solution, by rearranging the equation. No. Moles (mol) = Molarity (M) x Volume (L) = 0.5 x 2. = 1 mol.
- For NaCl, the molar mass is 58.44 g/mol. Now we can use the rearranged equation. Mass (g) = No. Moles (mol) x Molar Mass (g/mol) = 1 x 58.44. = 58.44 g.
What is the weight of air?
We know that air weighs 14.7 psi or pounds per square inch at sea level – meaning about 15 pounds are pressing down on every square inch of you.
What is the molar volume of air?
22.4 L mol
What would the volume of one mole of air be at 20°C on top of Mauna Kea, Hawa’ii (altitude 4.2 km) where the air pressure is approximately 60 kPa? The standard molar volume 22.4 L mol–1 is a value worth memorizing, but remember that it is valid only at STP.
What is the average weight of air?
At sea level, on average, the weight of the air above this unit area would weigh 14.7 pounds! The pressure applied by this air on the unit area would be 14.7 pounds per square inch. Meteorologists use a metric unit for pressure called a millibar. Average pressure at sea level is 1013.25 millibars.
How do you find moles of air?
To find the number of moles, divide the volume of your room by the volume of 1 mol of air.
Is o2 molar mass 32?
The molar mass of O2 is 32 gram per mole.
