A. The mass of the water in the compound is 1 g
B. The number of mole of water is 0.056 mole
C. The mass of the copper in the compound is 0.71 g
D. The number of mole of copper is 0.011 mole
E. The mass of the chlorine in the compound is 0.79 g
F. The number of mole of chlorine is 0.022mole
How do I determine the mass and mole of the water?
We can obtain the mass of the water as follow:
- Mass of hydrate = 2.50 g
- Mass of anhydrou = 1.50 g
- Mass of water = ?
Mass of water = Mass of hydrate - Mass of anhydrous
Mass of water = 2.50 - 1.50
Mass of water = 1 g
We can obtain the mole of water as follow:
- Mass of water = 1 g
- Molar mass of water = 18 g/mol
- Mole of water =?
Mole = mass / molar mass
Mole of water = 1 / 18
Mole of water = 0.056 mole
How do I determine the mass and mole of copper?
The mass of copper is 0.71 g
Thus, the mole of copper can be obtained as follow:
- Mass of copper = 0.71 g
- Molar mass of copper = 63.55 g/mol
- Mole of copper =?
Mole = mass / molar mass
Mole of copper = 0.71 / 63.55
Mole of copper = 0.011 mole
How do I determine the mass and mole of chlorine?
The mass of chlorine can be obtained as follow
- Mass of anhydrou = 1.50 g
- Mass of copper is 0.71 g
- Mass of chlorine =?
Mass of chlorine = Mass of anhydrou - Mass of copper
Mass of chlorine = 1.50 - 0.71
Mass of chlorine = 0.79 g
Thus, the mole of chlorine can be obtained as follow:
- Mass of chlorine = 0.79 g
- Molar mass of chlorine = 35.5 g/mol
- Mole of chlorine =?
Mole = mass / molar mass
Mole of chlorine = 0.79 / 35.5
Mole of chlorine = 0.022mole
