    Chemistry for Physiology
    Given that urea has the formula H2NCONH2 and the atomic weights H = 1, C = 12, N = 14 and O = 16, what is the mass of 1 mol of urea?
    Multiply the number of atoms of each element (H, C, N, O) in the formula by the element’s atomic weight to get mass of a mole. Hence: (4 × 1) + (1 × 12) + (2 × 14) + (1 × 16) = 4 + 12 + 28 + 16 = 60 g.
