What is the molar mass of a substance, if 0.4 mole of the substance has a mass of 25.0g?
Answer Details
The molar mass of a substance is the mass of one mole of the substance. We are given that 0.4 mole of the substance has a mass of 25.0 g.
To find the molar mass, we can use the formula:
Molar mass = Mass / Number of moles
Plugging in the given values, we get:
Molar mass = 25.0 g / 0.4 mol
Simplifying this expression, we get:
Molar mass = 62.5 g/mol
Therefore, the molar mass of the substance is 62.5 g/mol.
Answer: 62.5 g
