I think the answer would be b because your throat is reacting to the cough?
First, you need to find the mass of 1 mol of sugar. Mass, or molar mass, can simply be found by adding the masses of the individual elements. These are given to you on the periodic table.

12 x 12.011 grams (molar mass of Carbon) = 144.132 g
22 x 1.008 grams (molar mass of Hydrogen) = 22.176 g
11 x 15.999 grams (molar mass of Oxygen) = 175.989 g
Add all of the pieces together.
144.132 g + 22.176 g + 175.989 g = 342.297 grams
So, if one mole has 342.297 grams, then 7.35 of that amount will be your answer.
342.297 g/mol x 7.35 mol = 2,515.88 grams
Answer:
Explanation:
<u>1) Data:</u>
<em />
a) V = 75.0 liter
b) n = 15.82 mol
c) p = 546.8 kPa
d) T = ?
<u>2) Formula:</u>
- Ideal gas equation: pV = nRT
Where:
- n = number of moles
- V = volume
- p = absolute pressure
- T = absolute temperature
- R = Universal Gas constat: 8.314 kPa - liter / K-mol
<u>3) Solution:</u>
a) <u>Solve the equation for T</u>:
b) <u>Substitute and compute</u>:
- T = 546.8 kPa × 75.0 l iter / (15.82 mol × 8.314 kPa-liter/K-mol) = 312 K
(since the volume is expressed with 3 significant figures, the answer must show also 3 significant figures)
