use the following balanced equation to answer the questions: 2mg + o₂ → 2mgo there are 2 moles of mg present. the molar mass of magnesium is 24.31 g/mol. what mass of magnesium is present?

use the following balanced equation to answer the questions: 2mg + o₂ → 2mgo there are 2 moles of mg present. the molar mass of magnesium is 24.31 g/mol. what mass of magnesium is present?

Answer

Explanation:

Step1: Recall mass - mole relationship formula

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

Step2: Identify given values

We are given that $n = 2\ mol$ (number of moles of Mg) and $M=24.31\ g/mol$ (molar mass of Mg).

Step3: Calculate the mass

Substitute the values into the formula: $m=2\ mol\times24.31\ g/mol$. $m = 48.62\ g$

Answer:

$48.62\ g$
