Suppose you have 3.00*1018 reams of lead (pb). how many lead atoms do you have? express the number of atoms numerically.

Why is a chemical indicator added to the flask in which a titration will occur? to show when enough base has been added to determine the starting pH of the solution to neutralize the acid before adding the base to identify the starting volume of
