Answer: Total pressure of the gas will be 0.716atm.
Explanation: We are given a gas having initial conditions as
V = 27L
T = 32°C = 305K
P = 2.5atm
As the gas remains same, number of moles of a gas will also be same for initial and final conditions. To calculate the number of moles, we use ideal gas equation, which is,
.......(1)
where, R = gas constant =
For calculating number of moles:
Putting the values of initial condition in this equation, we get
n = 2.696 mol
Now, the final conditions are,
V = 88.0L
T = 12°C = 285K
n = 2.696 mol (calculated above)
P = ? atm
Again using equation 1, we get
P = 0.716atm.
Answer:- 27.7 grams of are produced.
Solution:- The balanced equation is:
let's convert the grams of each reactant to moles and calculate the grams of the product and see which one gives least amount of the product. This least amount would be the answer as the least amount we get is from the limiting reactant.
Molar mass of = 207.2+2(126.90) = 461 gram per mol
let's do the calculations for the grams of the product for the given grams of each of the reactant:
=
=
From above calculations, NaI gives least amount of , so the answer is, 27.7 g of
are produced.
