How Many Moles are in 68 Grams of Copper Hydroxide?
Copper hydroxide is an inorganic compound with the chemical formula Cu(OH) 2. It is a pale blue or green solid that is insoluble in water. Copper hydroxide is used in a variety of applications, including as a fungicide, a mordant in dyeing, and a catalyst in organic reactions.
Overview
A mole is a unit of measurement used to express the amount of a substance. It is defined as the amount of substance that contains as many elementary entities as there are atoms in 0.012 kilograms of carbon-12.
The relationship between moles and mass is given by the following equation:
moles = mass (grams) / molar mass (grams per mole)
The molar mass of copper hydroxide is 97.56 grams per mole.
Calculations, How many moles are in 68 grams of copper hydroxide
To convert 68 grams of copper hydroxide to moles, we use the following formula:
moles = mass (grams) / molar mass (grams per mole)
Substituting the given values into the equation, we get:
moles = 68 grams / 97.56 grams per mole
Therefore, 68 grams of copper hydroxide is equal to 0.697 moles.
Chemical Equation
The balanced chemical equation for copper hydroxide is:
Cu(OH)2→ CuO + H 2O
In this equation, one mole of copper hydroxide produces one mole of copper oxide and one mole of water.
Therefore, the number of moles of copper hydroxide in the equation is equal to the number of moles calculated in step 2, which is 0.697 moles.
Applications
Copper hydroxide is used in a variety of applications, including:
- As a fungicide
- As a mordant in dyeing
- As a catalyst in organic reactions
- As a pigment in paints and ceramics
- As a water treatment chemical
The number of moles of copper hydroxide needed for a specific application will depend on the desired outcome.
