7.20594 x 10^20
First you must determine how many moles of P3O5 you have. This is done by using the formula
Number of moles (n) = mass in grams of substance (m) /divided by/ Molar mass (M) [this is the sum of the atomic mass of all atoms in the compound]
n = 0.170 / P (31 x 2) + O (16 x 5)
n = 0.170 / 142
n = 0.001197 moles
Then you use avagadros number 6.02 x10^23 this is the number of atoms in one mole of any substance. Since you have 0.001197 moles you multiply the number of moles by avagadros number
0.001197 x (6.02 x 10^23)
= 7.20594 x 10^20 atoms
ok so when it comes to atoms there is the same amount for example the hydrogen atom has 1 proton 1 electron but no neutrons while the carbon atom has 6 protons 6 neutrons and 6 electrons so your answer would be b!
The mass of carbon dioxide that is produced will be 31,671 grams or 31.671 kg
<h3>Stoichiometric calculations</h3>
First, the equation of the reaction:
The mole ratio of propane burned to carbon dioxide produced is 1:3.
The density of propane gas is 0.621 g/mL, thus, 17.0 L of propane will weigh:
Density = mass/volume, mass = 0.621 g/mL x 17000 = 10,557 g
Mole of 10,557 g of propane = 10557/44.1 = 239.39 moles
Equivalent mole of carbon dioxide produced = 239.39 x 3 = 718.16 moles
Mass of 718.16 moles carbon dioxide = 718.16 x 44.1 = 31,671 grams or 31.671 kg

Answer: 1 . Unsaturated Solution
2. Saturated Solution
Explanation:
1 ..tedsaturauntionsolu----------- Unsaturated Solution
2. ratedsatulutisoon--------------Saturated Solution
An Unsaturated solution is defined as a solution which contains an amount of solute that dissolves completely since the amount of solute is still less than the maximum amount that can readily dissolve in such solution and an additional amount of solute if added continues to dissove in the solution. Here the solution is still less than the equilibrium point.
example include. Addition of salt or sugar in water and it dissoves completely.
A saturated solution is defined as A solution which contains a maximum amount of solute that an additional solute will no longer be capable of being dissolved further since its equilibrium point has been reached.
Example- The addition of sugar to water till it no longer dissolves
Carbonated water is a saturated solution saturated with carbon as can be seen in the air bubbles it gives offf in form of carbon.
