Document Summary

Chm1311 chapter 1 assignment: calculate the number of moles in 9. 88 g of b. Mole of b=0. 914 mol: calculate the number of atoms in 3. 10 mg of c. g= 3. 10mg x 1g/1000mg g=0. 0031g. =1. 55e20: determine the molecular formula and calculate the molar mass (in g/mol) of tyrosine, the essential amino acid. The molecular formula is c9h11o3 and the molar mass is 181. 21g/mol: the u. s. Recommended daily allowances (rdas) of several vitamins follow. In each case, calculate how many molecules are in the u. s. rda: 60. mg vitamin c, c6h8o6. g=60mg x 1g/1000mg. = 2. 1e20 molecules: 400. mg folic acid, c19h19n7o6 g=400mg x 1g/1000mg. # of c19h19n7o6 atoms= 5. 46e20: 1. 70 mg vitamin b2 (riboflavin), c17h20n4o6. = 2. 72e18: a chemist places 3. 41 g of sodium carbonate in a 250. 0 ml volumetric flask and fills it to the mark with water. Calculate the concentrations of the major ionic species in units of mol/l (m): sodium ion concentration.
