P x V = n x R x T
1.00 x V = 3.50 x 0.082 x 273
1.00 x V = 78.351
V = 78.351 / 1.00
V = 78.351 L
Stoichiometry is the relationship between the relative quantities of substances taking part in a reaction or a compound. this is normally a ratio of whole integers.
The homologous structures and the analogous structures of different species.
Answer:
moles
Explanation:
We are given:
Vapor pressure of water = 19.8 torr
Total vapor pressure = 752 torr
Vapor pressure of oxygen gas = Total vapor pressure - Vapor pressure of water = (752 - 19.8) torr = 732.2 torr
To calculate the amount of oxygen gas collected, we use the equation given by ideal gas which follows:
where,
P = pressure of the gas = 732.2 torr
The conversion of P(torr) to P(atm) is shown below:
So,
Pressure = 732.2 / 760 atm = 0.9634 atm
V = Volume of the gas = 23 mL = 0.023 L
T = Temperature of the gas =
R = Gas constant =
n = number of moles of oxygen gas = ?
Applying the equation as:
0.9634 atm × 0.023 L = n × 0.0821 L.atm/K.mol × 295.15 K
⇒n = moles
