Answer:
3.86x10^24 molecules
Explanation:
From the question given, the following data were obtained:
Volume of ice = 0.5cup
1 cup = 240mL
0.5cup = 0.5 x 240 = 120mL
Density of ice = 0.9167 g/mL
molar mass of water = 18.015g/mol
First let us calculate the mass of ice. This is illustrated below:
Density = Mass /volume
Mass = Density x volume
Mass = 0.9167 x 120
Mass of ice = 110.004g = Mass of water
From Avogadro's hypothesis, we understood that 1mole of any substance contains 6.02x10^23 molecules. This means that 1mole of water will also contain 6.02x10^23 molecules.
1mole of water = 18.015g
If 1 mole (18.015g) contains 6.02x10^23 molecules,
Therefore, 110.004g of water will contain = (110.004x6.02x10^23)/18.015 = 3.86x10^24 molecules
Answer:
Total pressure = 1109.2 torr
Explanation:
Given data:
Partial pressure of cyclopropane = 334 mmHg
Partial pressure pressure of oxygen = 1.02 atm
Total pressure of mixture = ?
Solution:
Formula:
Total pressure = P of C₃H₆ + P of O₂
1 atm = 760 torr = 760 mmHg
1.02 atm × 760 torr / 1atm = 775.2 torr
Total pressure = P of C₃H₆ + P of O₂
Total pressure = 334 torr + 775.2 torr
Total pressure = 1109.2 torr
Answer:
Speed of light is measured in vacuum and is equal to 671 million miles per hour, 1080 million kilometers per hour, 173 astronomical meters per second.
The exact value of speed of light is considered to total 299,792,458 meters per second
