How many grams of carbon dioxide are in 6.75 moles?

Answer 1

Write chemical formula for carbon dioxide and calculate molar mass (g/mol) from counting number of carbon and number of oxygen and taking sum of their atomic masses. Carbon is usu 12.0 g/mol and oxygen is usu 16.0 g/mol.

Then use calculated molar mass to convert from grams of carbon dioxide to moles of carbon dioxide.
