Question
What is the molar mass of a compound?A.The mass in grams of 1 mole of the compoundB.The number of moles in 1 g of the compoundC.The number of moles in a molecular formulaD.The number of atoms in 1 mole of the compound
Solution
The molar mass of a compound is A. The mass in grams of 1 mole of the compound.
Here's a step-by-step explanation:
-
The molar mass of a compound is the mass of one mole of that particular substance.
-
The unit for molar mass is grams per mole (g/mol).
-
It can be calculated by summing the masses of all the atoms in a molecule of the compound, each multiplied by the number of times that element occurs in the compound.
-
For example, the molar mass of water (H2O) would be calculated as follows: (2 * atomic mass of Hydrogen) + (1 * atomic mass of Oxygen) = approximately 18 g/mol.
-
So, the molar mass of water is 18 g/mol, which means that 1 mole of water has a mass of 18 grams.
Therefore, option A is the correct answer.
