A heliox tank contains 32% helium and 68% oxygen. The total pressure in the tank is 475 kPa. What is the partial pressure of hel

Paladinen [302]

Answer:

152 kPa = Partial pressure O₂

Explanation:

Data by percent is the molar fraction . 100.

Molar fraction of Helium = 32/ 100 → 0.32

Molar fraction of O₂ = 68/100 → 0.68

Sum of molar fractions in a mixture = 1

0.68 + 0.32 = 1

If we apply the molar fraction, we can determine the partial pressure.

Mole fraction = Partial pressure / Total pressure

0.32 = Partial pressure O₂ / 475kPa → 0.32 . 475 kPa = Partial pressure O₂

152 kPa = Partial pressure O₂

PLS HELPPP How many moles of oxygen atoms (not molecules) are present in 6.41×1025 molecules of dinitrogen pentoxide (N2O5)? 1.

olga55 [171]

Answer:

(4) 266 moles

Explanation:

We have Dinitrogen Pentoxide N2O5

6.41*10^25 molecules are given

No of Moles of N2O5 = $\frac{No of Molecules }{Avogadro's Number}$

= $\frac{6.41 * 10^25}{6.022*10^23}$

= 106.5 mol

Now using Unitary Method

2 Mole of Nitrogen pentoxide require 5 mole of Oxygen to form N2O5

1 mole of N = $\frac{5}{2}*O$

In 106.5 mole of N = $\frac{5}{2}*106.5$ = 266.25 mole

So, 6.41*10^25 molecules of N2O5 will require 266.25 mole of Oxygen atoms.
