Explanation:
No of molecules=0.500×6.023×10²³=3.011×10²³ molecules
The new volume be if the pressure inside the balloon was reduced to 58kpa is 2.58 L.
<h3>What is ideal gas equation?</h3>
Ideal gas equation PV=nRT gives idea about the behavior of gases at different conditions and for this question the equation becomes:
P₁V₁ = P₂V₂, where
P₁ = initial pressure = 115.3 kpa
V₁ = initial volume = 1.3 L
P₂ = final pressure = 58 kpa
V₂ = final volume = ?
On putting all these values in the above equation, we get
V₂ = (115.3)(1.3) / (58) = 2.58 L
Hence resultant volume of gas is 2.58 L.

Answer:
40/220 ×100=18.6 is all I got I know that by heart so um yea
Explanation:
First step is to balance the reaction equation. Hence we get
P4 + 5 O2 => 2 P2O5
Second, we calculate the amounts we start with
P4: 112 g = 112 g/ 124 g/mol – 0.903 mol
O2: 112 g = 112 g / 32 g/mol = 3.5 mol
Lastly, we calculate the amount of P2O5 produced.
2.5 mol of O2 will react with 0.7 mol of P2O5 to produce 1.4
mol of P2O5.
This is 1.4 * (31*2 + 16*5) = 198.8 g
Dividing the mass by the volume.
