100 mL of NaCl solution was titrated with 50 mL of 0.2 M AgNO3 solution. How many grams of AgCl were produced? M(AgCl)=143.2 g/mol
A cache of Hebrew manuscripts known as the Dead Sea Scroll was found in 1947. The specific activity of Carbon-14 in the linen wrappings of the book of Isaiah was about 0.200 disintegration per second per gram (dps g-1.). Carbon-14 in living materials has
a specific activity of 0.255 dps g-1. The half-life of Carbon-14 is
5.73 x103 years. Carbon-14 decay by First order rate law. Calculate the approximate age of the linen.
