Answer:
Number of moles of Al = 0.02 mol
Number of moles of CuCl₂ = 0.02 mol
Explanation:
Given data:
Mass of CuCl₂ = 2.50 g
Moles of CuCl₂ = ?
Solution:
Formula:
Number of moles = mass / molar mass
Molar mass of CuCl₂ = 63.546 + 35.5 ×2
Molar mass of CuCl₂ = 134.546 g/mol
Now we will put the values in formula:
Number of moles = 2.50 g / 134.546 g/mol
Number of moles = 0.02 mol
Given data:
Mass of Al = 0.50 g
Moles of Al = ?
Solution:
Formula:
Number of moles = mass / molar mass
Molar mass of Al = 27 g/mol
Now we will put the values in formula:
Number of moles = 0.50 g / 27 g/mol
Number of moles = 0.02 mol
Hello!
GAS SOLUBILITY INCREASES:
• O2 in the blood of a person who is in a hyoerbaric chamber.
• The partial pressure of an anesthetic gas is increased.
• The temperature is decreased.
GAS SOLUBILITY DECREASES:
• CO2 In a can of soda as it warms to room temperature.
• The pressure of a gas over a solvent is decreased.
I really hope this helped you! :)
