Here, we may apply the equation of state for an ideal gas, which is:
PV = nRT
We may substitute the number of moles, n, with:
moles = mass / molecular mass
PV = mRT/Mr
Mr = (mRT)/PV
Substituting the values:
Mr = (81.5 * 0.082 * 307) / (1.75 * 4.92)
Mr = 238.3
The molar mass of the gas is 238.3 grams per mole.
Answer:
4.525% is the percentage by volume of oxygen in the gas mixture.
Explanation:
Total pressure of the mixture = p = 4.42 atm
Partial pressure of the oxygen = 
Partial pressure of the helium = 
(Dalton law of partial pressure)
According Avogadro law:
(At temperature and pressure)
Volume occupied by oxygen gas =
Total moles of gases = n = 1 mol
Total Volume of the gases = V
Percent by volume of oxygen in the gas mixture:
Because they could have an explosive reaction and could possibly hurt you
Answer:
the abundance of non-native plants. this MAY be right.
Explanation:
i thought it would be an increase in pollution.
A gas is something that takes up the space of the container, because it doesn't have a fixed shape.
