A 10.0-mL sample of 1.0 M NaHCO3 (sodium bicarbonate) is titrated with 1.0 M HCl (hydrochloric acid). Give the pH at the indicated volumes. 1. pH after 0 mL HCl added,
2. pH after 1.0 mL HCl added,
3. pH after 9.5 mL HCl added,
4. pH after 10.0 mL HCl added (equivalence point),
5. pH after 10.5 mL HCl added, and
6. pH after 12.0 mL HCl added.

Calculate: select the worksheet tab. this tab you calculate the analyte concentration.  fill in the first set of boxes ("moles h2so4" and "moles naoh") based on the coefficients in the balanced equation. (if there is no coefficient, the value is 1.)  record the appropriate volumes in the "ml naoh" and "ml h2so4" boxes.  record the concentration of the titrant in the m naoh box. click calculate. what is the concentration listed

How many moles of lead are in 1.50 x 10^12 atoms of lead? could you explain the answer as well and not just give it to me i am refreshing for finals and i need to know how to do it
