Answer:
The final volume of the balloon is = 28.11 L
Explanation:
Initial pressure = 1.03 atm = 104.325 K pa
Initial temperature = 26 °c = 299 K
Initial volume = 22.4 L
Final temperature = 22 °c = 295 K
Final pressure = 0.81 atm = 82 K pa
We know that
Put all the values in above formula we get
= 28.11 L
This is the final volume of the balloon.
Answer:
4.87×10²⁴ molecules
Explanation:
Given data:
Mass of glucose = 1456 g
Number of molecules = ?
Solution:
Number of moles of glucose:
Number of moles = mass/molar mass
Number of moles = 1456 g/ 180.156 g/mol
Number of moles = 8.1 mol
1 mole of glucose contain 6.022×10²³ molecules
8.1 mol × 6.022×10²³ molecules / 1 mol
48.7×10²³ molecules
4.87×10²⁴ molecules
the answer is because when you research that would be the answer
An extensive property is a property that depends on the amount of matter in a sample.
The correct answer is e.
Entropy is the measure of the disorderliness in a changing and closed system. The higher the entropy in a system, the higher the disorderliness and the lower the tendency of the system to usefully work.
