It would be 3C + 4H2 -> C3H8
To calculate the molar mass of substance, divide the number of moles by the given mass of substance.
The quantity of a substance is known as a mole. You can measure it in terms of grams, liters, atoms, molecules, or particles.
Use the substance's molar mass to convert between grams and moles. Divide the given mass by the number of moles to convert from moles to molar mass.
Using the formula, Number of moles = Given mass/ molar mass
The molar mass of a substance can be calculated as-
Molar mass = Given mass/number of moles
