The unit price per ounce is $0.55. The correct option is b. $0. 55
From the question,
We are to calculate the unit price per ounce
First, we will calculate the how many ounces are in 283.5 grams
From the give information,
28.35 g = 1 ounce
∴ 283.5 g = ounces
283.5g = 10 ounces
Now,
Since the unit price is 283. 5 grams at $5. 48
That means
The unit price is 10 ounces at $5. 48
Now,
If 10 ounces cost $5.48
Then,
1 ounce will cost
1 ounce will cost $0.548 ≅ $0.55
Hence, the unit price per ounce is $0.55. The correct option is b. $0. 55

(8.08x10^24 H atoms)(3 C atoms/8 H atoms)
=3.03x10^24 C atoms
3.03x10^24+8.08x10^24=1.111x10^25 atoms total
(1.111x10^25)/(6.02x10^23)=18.4551495 mol C3H8
18.4551495(44.01)=812.2111296g C3H8
The best description for the relationship between the products and the reactants in an exothermic reaction is C. The potential energy of the products is less than the potential energy of the reactants.
Answer : The final temperature of balloon will be, 907 K
Explanation :
Charles' Law : It states that volume of the gas is directly proportional to the temperature of the gas at constant pressure and number of moles.
Mathematically,
where,
are the initial volume and temperature of the gas.
are the final volume and temperature of the gas.
We are given:
Putting values in above equation, we get:
Therefore, the final temperature of balloon will be, 907 K
