A balloon contains 146.o mL of gas confined at a pressure of 1.30 atm and a temperature of 5.0 C If the pressure doubles and the

temperature decreases to 2.0 C what will the volume of the gas be in the balloon.

If 4.00 moles of oxygen gas, 3.00 moles of hydrogen gas, and 1.00 mole of nitrogen gas are combined in a closed container at sta

neonofarm [45]

Answer:

Partial pressure of H₂ is 0.375 atm

Explanation:

We apply the mole fraction to solve this.

Standard pressure is 1 atm

Mole fraction of a gas = Moles of gas / Total moles

Mole fraction of pressure = Partial pressure of gas / Total pressure

Both values are the same

Total moles = 4 moles of O₂ + 3 moles of H₂ and 1 mol of N₂ = 8 moles

3 moles H₂ / 8 moles = Partial pressure H₂ / 1 atm

(3 / 8 ) .1 = 0.375 atm → Partial pressure of H₂

A compound is composed of 85.6% Carbon and the rest is Hydrogen. The molecular mass of the compound is 42.078g/mol. What is the

s344n2d4d5 [400]

The molecular formula for the compound is $C_{3} H_{6}$

<u>Explanation</u>:

As with all of these problems, we assume 100 g of an unknown compound.

And thus, we determine the elemental composition by the given percentages.

Moles of carbon = 85.64 / 12.011

= 7.13 mol.

Moles of hydrogen = 14.36 / 1.00794

= 14.25 mol.

There are 2 moles of hydrogen per mole of carbon. And thus the empirical formula is CH $_{2}$ .

And molecular formula = n × (empirical formula)

Thus, 42.08 = n × (12.011 + 2 × 1.00794)

And thus n = 3, and molecular formula = $C_{3} H_{6}$

2 years ago a 4.00 l flexible container holds a sample of hydrogen gas at 153 kpa. if the pressure increases to 203 kpa and the

garri49 [273]

To solve this we assume that the gas is an ideal gas. Then, we can use the ideal gas equation which is expressed as PV = nRT. At a constant temperature and number of moles of the gas the product of PV is equal to some constant. At another set of condition of temperature, the constant is still the same. Calculations are as follows:

P1V1 =P2V2

V2 = P1 x V1 / P2

<span>V2 = 153 x 4 / 203</span>

V2 = 3 L
