i have to do a "chemistry of cooking" project for my chem class. for the project i need to convert pounds, grams, and ounces into moles, but i do not know how. for example, i need to convert 453.5g of beef into mols. how do i do that? do i need to know the chemical formula of the beef?

• chemistry -

Either the formula or the molar mass of the principal material. moles = grams/molar mass.

• chemistry-DrBob222 -

but i do not know the molar mass.

• chemistry -

Nor do I. You might look up the molar mass of DNA or protein and fat and take some estimate from that. I don't know. Perhaps another tutor has a suggestion.
