The average molecular mass of an amino acid is 110 g/mol.Calculate the approximate number of amino acids in aprotein that has a molecular mass of 36,500 g/mol.

About how many moles is 112 grams of CaO? 2.0 moles 0.1 moles 0.2 moles 1.1 moles None of the above

Can a small sample of one substance have the same mass as a large sample of a different substance?  Explain/give simple examples

Anthropologists can estimate the age of a bone or other organic matter by its carbon-14 (C-14) content. The C-14 in a living organism is constant until the organism dies, after which C-14 decays with first-order kinetics and a half-life of 5730 years. Suppose a bone from an ancient human contains 19.5% of the C-14 found in living organisms. Calculate the age of the bone. 9.

Calculate the radius of a MVatom, given that MV has a BCC crystal structure, a density of 7.14g/cm3, and an atomic weight of 418.3g/mol.
