Problem 4.38

Two isotopes of rubidium occur naturally, with 37 85 Rb at 72.17% 184.91 amu2 and 87 37Rb at 27.83% 186.91 amu2. Calculate the atomic mass for rubidium using the weighted average mass method.

Step-by-Step Solution:
Step 1 of 3

Conversion Between Different Measurement Systems If multiplying a number by one of these conversion factors you are not changing the value of the number in anyway just changing the unit. Use dimensional analysis to convert (let the units do the work) 63.5 in to ft (63.5 in / 1) x (1 ft / 12 in) (On paper the in would be diagonal from one another therefor cancelling each other out leaving only ft behind. Note that 1 ft is an exact number just like 12 in therefor they do not have sig fig like 63.5 so only 3 sig fig.) = 5.29 ft 10.070 qt -> L (10.070 qt / 1) x (.9463 L / 1 qt) = (10.070 x .9463 L) = 9.529 L Metric conversions used to express very large or small numbers.
