The mass in amu of one molecule of a compound is directly proportional to the mass in grams of one mole of that compound.
To describe the relationship between the mass in atomic mass units (amu) of one molecule of a compound and the mass in grams of one mole of that compound, we can say: "The mass in amu of one molecule of a compound is numerically equal to the mass in grams of one mole of that compound."
To understand this relationship, we need to follow a few steps:
1. Determine the molar mass of the compound: The molar mass is the mass in grams of one mole of a substance. It can be obtained by summing up the atomic masses of all the atoms in the chemical formula of the compound. This value is usually given in periodic tables or can be calculated using atomic masses of individual elements.
2. Convert the molar mass to atomic mass units (amu): To convert the molar mass from grams to amu, we use the fact that 1 gram is equal to the Avogadro constant (6.022 x 10^23) amu. This constant represents the number of particles (atoms, molecules) in one mole of a substance.
3. Compare the masses: Once we have converted the molar mass from grams to amu, we can see that the mass in amu of one molecule of the compound is the same as the converted mass in grams of one mole of that compound.
Remember to always use the molar mass when making calculations involving moles and grams, as it provides an accurate conversion factor.
