Calculate the molar mass of: 0.5 mol of a covalent compound with a mass of 49 g.

To calculate the molar mass of the compound, we first need to determine the mass of 1 mol of the compound.

Given that 0.5 mol of the compound has a mass of 49 g, we can calculate the mass of 1 mol as follows:

Mass of 1 mol = Mass of 0.5 mol / 0.5
Mass of 1 mol = 49 g / 0.5
Mass of 1 mol = 98 g

Therefore, the molar mass of the compound is 98 g/mol.

Step 1: Convert moles to grams

Molar mass = Mass / Number of moles

Mass = Molar mass x Number of moles

49 g = Molar mass x 0.5 mol

Step 2: Solve for molar mass

Molar mass = 49 g / 0.5 mol

Molar mass = 98 g/mol

Therefore, the molar mass of the covalent compound is 98 g/mol.
