use the following balanced equation to answer the questions: 3rb + p → rb₃p there are 3 moles of rb present. the molar mass of rubidium is 85.47 g/mol. what mass of rubidium is present?

use the following balanced equation to answer the questions: 3rb + p → rb₃p there are 3 moles of rb present. the molar mass of rubidium is 85.47 g/mol. what mass of rubidium is present?

Answer

Explanation:

Step1: Recall mass - mole formula

The formula to calculate mass ($m$) from moles ($n$) and molar mass ($M$) is $m = n\times M$.

Step2: Substitute given values

We know $n = 3\ mol$ (moles of Rb) and $M=85.47\ g/mol$ (molar mass of Rb). So $m=3\ mol\times85.47\ g/mol$.

Step3: Calculate the mass

$m = 256.41\ g$.

Answer:

$256.41\ g$
