Answer:

1550.8

Explanation:

This is the ideal gas equation:

PV=nRT

We can rearrange the ideal gas equation to solve for the pressure of the nitrogen gas.

P=nRT/ V

We can find the pressure of the nitrogen gas by plugging in the values for the moles of gas, temperature, and volume. Since we want the pressure in units of Torr we use the R value62.36358L Torr K−1 mol-1

P=nRT/ V

(0.316 mol )(62.36358 L*Torr/K*mol)(315 K) / 4.00 L =1550 Torr

The correct answer is 1550

At a particular temperature, the solubility of Kr in water is 0.060 M when the partial pressure is 0.90 atm. What partial pressu
elena55 [62]

At a particular temperature, the solubility of He in water is 0.060 M when the partial pressure is 0.90 atm. 2.27 atm is the partial pressure of Kr would give a solubility of 0.150 M.

<h3>What is Henry's Law ?</h3>
  • According to Henry's law, the weight of a gas dissolved by a liquid is proportional to the pressure of the gas onto the liquid.
  • With very few exceptions, a solute molecule in an extremely diluted solution will only have solvent molecules as its close neighbors. This means that the likelihood that a specific solute molecule will escape into the gas phase is predicted to be independent of the total concentration of solute molecules.

Solution:

The solubility of gas is directly proportional to partial pressure. It is expressed as:

S = K_ h \times P _g_a_s

where, S = Solubility of gas

K_h = Henry's Law constant

P_g_a_s = Partial pressure of gas

Now, put the values in above expression we get

0.060M = K_h × 0.9 atm

   K_h =  = 0.066 M/atm

Now we have to find the partial pressure of He

0.150 M = 0.066 M/atm × P_g_a_s

P_g_a_s = 2.27 atm

A laboratory analysis of an unknown sample yields 74.0% carbon, 7.4% hydrogen, 8.6% nitrogen, and 10.0% oxygen. What is the empi
kirza4 [7]
Let us assume that there is a 100g sample present. The respective mass of each element will then be:
C: 74 g
H: 7.4 g
N: 8.6 g
O: 10 g
Now, we divide each constituent's mass by its Mr to obtain the moles of each
C: (74 / 12) = 6.17
H: (7.4 / 1) = 7.4
N: (8.6 / 14) = 0.61
O: (10 / 16) = 0.625
Dividing by the smallest number:
C: 10
H: 12
N: 1
O: 1
Thus, the empirical formula is
C10H12NO
