Suppose you have 19.2 g of Cu. What number of moles of Cu is present? Report your answer to 3 signifiant figures.
how many grams in 1 mole?
Divide that into 19.2g
To find the number of moles of copper (Cu), we need to use the formula:
moles = mass / molar mass
The molar mass of copper (Cu) is 63.546 g/mol.
Substituting the given values:
moles = 19.2 g / 63.546 g/mol
Calculating the result:
moles ≈ 0.302 mol
Therefore, the number of moles of copper (Cu) present is approximately 0.302 mol.
To find the number of moles of Cu present, we need to use the molar mass of copper (Cu).
The molar mass of copper is approximately 63.55 g/mol.
To calculate the number of moles, we can use the formula:
moles = mass / molar mass
Substituting the given values:
moles = 19.2 g / 63.55 g/mol
moles ≈ 0.302 moles
Therefore, the number of moles of Cu present is approximately 0.302 moles.
