An experimenter has determined the relative abundance (fractional abundance) of the five naturally occurring isotopes of platinum: Pt - 192 0.80% Pt - 194 32.96% Pt - 195 33.86% Pt - 196 25.36% Pt - 198 7.22% From the above data, determine the average (and weighted) molecular weight of platinum. Do not just look it up since the above data is from an experimenter and may not be exact to accepted values.
a. 195.078
b. 195.178
c. 195.507
d. 195.207
e. 195.707
