Unformatted text preview: state computed in part (b). Thus the ratio is (0 . 0100)(1) = 0 . 0100. (e) This is similar to part (d) above. Since only 1 . 00% of the 226 Ra remains, the ratio N 226 /N 210 is 1 . 00% of that of the equilibrium state computed in part (c), or (0 . 0100)(70 . 8) = 0 . 708. (f) Since the actual value of N 226 /N 210 is 0.09, which much closer to 0.0100 than to 1, the sample of the lead pigment cannot be 300 years old. So Emmaus is not a Vermeer ....
