I have a question on my Chem homework. It's asking "How many molecules of N2O4 are in 76.3 g N2O4? The molar mass of N2O4 is 92.
evablogger [386]
Here, Molar mass of N2O4 = 92.02 g/mol
So, Number of molecules in 1 mole (92.02 g) = 6.023 * 10²³
Number of molecules in 76.3 g = 6.023 * 10²³ / 92.02  * 76.3
= 6.023 * 10²³ / 1.20
= 5 * 10²³ 

In short, Your Answer would be approx. 5 * 10²³ molecules

Hope this helps!

While in Europe, if you drive 107km per day, how much money would you spend on gas in one week if gas costs 1.10 euros per liter
Mumz [18]
That's a lot of conversions...
107*7 = 749km in one week
749/1.6 = 468.125 miles
468.125/39 = <span>12.0032051282 gallons of fuel needed
</span>1 gallon = 4.54609 litres
1.1(Cost per litre)*4.54609(Number of litres per gallon)*12.0032051282(Number of gallons needed) = <span>60.0244158814 euros cost per week
 </span>60.0244158814 * 1.26 = <span>75.6307640105 dollar cost per week

Four gases were combined in a gas cylinder with these partial pressures: 3. 5 atm N2, 2. 8 atm O2, 0. 25 atm Ar, and 0. 15 atm H
aksik [14]

The total pressure of the gas has been 11.9 atm.

The partial pressure has been the pressure exerted by the individual gas in the mixture.

According to the Dalton's law of Partial pressure, the pressure of the gas has been the sum of the partial pressure of each gas in the mixture.

<h3 /><h3>Computation for the pressure of gas</h3>

The given gas has partial pressure of Nitrogen, P_{N_2}=3.5\;\rm atm

The partial pressure of Oxygen, P_{O_2}=8\;\rm atm

The partial pressure of Argon, P_{Ar}=0.25\;\rm atm

The partial pressure of Helium, P_{He}=0.15\;\rm atm

The total pressure, (<em>P</em>) of the gas has been given as:

P=P_{N_2}\;+\;P_{O_2}\;+\;P_{Ar}\;+\;P_{He}\\&#10;P=3.5\;+8\;+\;0.25\;+\;0.15\;\text{atm}\\&#10;P=11.9\;\rm atm

The total pressure of the gas has been 11.9 atm.
