use the following balanced equation to answer the questions: 2h₂ + o₂ → 2h₂o there are 2 moles of h₂ present. the molar mass of hydrogen is 1.01 g/mol. what mass of hydrogen is present?

use the following balanced equation to answer the questions: 2h₂ + o₂ → 2h₂o there are 2 moles of h₂ present. the molar mass of hydrogen is 1.01 g/mol. what mass of hydrogen is present?

Answer

Answer:

2.02 g

Explanation:

Step1: Recall mass - mole formula

$m = n\times M$ where $m$ is mass, $n$ is number of moles, and $M$ is molar mass.

Step2: Identify given values

$n = 2\ mol$ (moles of $H_2$), $M=1.01\ g/mol$ (molar mass of $H_2$)

Step3: Calculate mass

$m=2\ mol\times1.01\ g/mol = 2.02\ g$
