Determination of the Mass of 2.55 Moles of Cu2CrO4
This article provides a comprehensive explanation of how to determine the mass of 2.55 moles of copper(II) chromate (Cu2CrO4). It covers the molecular mass of Cu2CrO4, the concept of moles and their relationship to mass, the formula for converting moles to mass, and the significance of this mass determination in various applications.
Molecular Mass of Cu2CrO4, Determine the mass of 2.55 mole cu2cro4
The molecular mass of a compound is the sum of the atomic masses of all the atoms in its molecule. To calculate the molecular mass of Cu2CrO4, we need to know the atomic masses of copper (Cu), chromium (Cr), and oxygen (O).
Atomic mass of Cu: 63.55 g/mol
Atomic mass of Cr: 52.00 g/mol
Atomic mass of O: 16.00 g/mol
The molecular mass of Cu2CrO4 is calculated as follows:
Molecular mass = (2 × Atomic mass of Cu) + (1 × Atomic mass of Cr) + (4 × Atomic mass of O)
Molecular mass = (2 × 63.55 g/mol) + (1 × 52.00 g/mol) + (4 × 16.00 g/mol)
Molecular mass = 123.55 g/mol + 52.00 g/mol + 64.00 g/mol
Molecular mass = 239.55 g/mol
Converting Moles to Mass
The mole is the SI unit of amount of substance. One mole of a substance contains 6.022 × 10 23particles (atoms, molecules, ions, or electrons) of that substance. The mass of one mole of a substance is called its molar mass.
The formula for converting moles to mass is:
Mass = Moles × Molar mass
To convert 2.55 moles of Cu2CrO4 to grams, we need to multiply the number of moles by the molar mass of Cu2CrO4.
Mass = 2.55 moles × 239.55 g/mol
Mass = 611.10 g
