Question

calculate the mass, in grams, of a single rubidium atom ($m_{rb}=85.468$ amu). express your answer in grams to four significant figures. view available hint(s) incorrect; try again review your calculations and make sure you

Explanation:

Step1: Recall conversion factor

1 amu = $1.66054\times 10^{-24}$ g

Step2: Calculate mass of rubidium atom

$m = 85.468\times1.66054\times 10^{-24}$ g
$m=85.468\times1.66054\times10^{- 24}\approx1.429\times 10^{-22}$ g

Answer:

$1.429\times 10^{-22}$ g
