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!

The answer is Point C because it is the lowest point
Answer:
3.58J/g°C is the specific heat of the metal
Explanation:
The specific heat of a material is defined as the energy that 1g of the material absorbs and produce the increasing in temperature in 1°C. The equation is:
Q = S*ΔT*m
<em>Where Q is energy = 1362J</em>
<em>S is specific heat of the material</em>
<em>ΔT is change in temperature = 42°C - 17°C = 25°C</em>
<em>And m is the mass of the material = 15.2g</em>
Replacing:
S = Q / ΔT*m
S = 1362J / 25°C*15.2g
<h3>3.58J/g°C is the specific heat of the metal</h3>
Answer:
8 waffles
Explanation:
First, find the limiting reagent. Divide the amount you have by the amount that is needed. The smallest number is the limiting reagent. <u>For this problem, the limiting reagent is oil.</u>
6 cups of flour/2 cups of flour = 3
9 eggs/3 eggs = 3 2 tbsp of oil/1 tbsp of oil = 2
This means that we can double the recipe since we have enough of each ingredient to make two batches. Multiply the entire equation by 2. This should give you 4 cups of flour + 6 eggs + 2 tbsp of oil ==> 8 waffles.
<u>You should theoretically get 8 waffles.</u>
