Question
Use the reaction: CH3COOH > CO2 + CH4. And use the table:
Element Molar Mass (g/mol)
Carbon 12.01
Hydrogen 1.01
Oxygen 16.00
A chemist will use a sample of 30 g of ethanol in an experiment. In 2 sentences make a justify a claim about the number of moles of ethanol the chemist will use by calculating the molar mass of ethanol and using it to find moles.

To calculate the number of moles of ethanol (C2H5OH), we first determine its molar mass: C (2 x 12.01 g/mol) + H (6 x 1.01 g/mol) + O (1 x 16.00 g/mol) = 46.08 g/mol. Given that the chemist has a sample of 30 g of ethanol, the number of moles can be calculated as 30 g / 46.08 g/mol = 0.651 moles, justifying the claim that the chemist will use approximately 0.651 moles of ethanol in the experiment.
