Question

the mole can be used as a conversion from the atomic to the macroscopic scale. in order to do this molar mass is needed. calculate the molar mass of each chemical formula. type in the numerical response, such as 32.56. round the molar mass of each chemical to two decimal places. rbbr

Explanation:

Step1: Find atomic masses

Rb (Rubidium) atomic mass: $85.47$ g/mol
Br (Bromine) atomic mass: $79.90$ g/mol

Step2: Sum atomic masses

Molar mass of RbBr = Atomic mass of Rb + Atomic mass of Br
$= 85.47 + 79.90$
$= 165.37$

Answer:

165.37
