Answer:
moles is measured in mol without an e
therefore, the formula for calculating for mole or the amount of substance in chemistry is mass per molar mass of which the molar mass has an SI unit of g/mol
therefore, let's substitute the figures into the equation
1. first solve for the molar mass of carbon
which is you double the atomic number of carbon
carbon has an atomic number of 6 so the relative molecular mass will be 2×6=12 g/mol
solving the question will be -->120g/12g/mol
which gives an answer of 10mol in the content
