Question

The molecular weight of hydrogen peroxide is $34$. What is the unit of molecular weight?

Answer 1

A chemical compound is created when two or more elements bonded together. Hydrogen peroxide is created from hydrogen and oxygen. The chemical formula for hydrogen peroxide is $H_2{O}_2$.
Answer and Explanation:
The molar mass of hydrogen peroxide is $34.01468g/mol$.
To calculate molar mass, you need to know the atomic mass of each of the chemical elements that make up the compound. You also need to know the formula for the compound, so you can identify how many atoms of each element are combined.
Hydrogen has an atomic mass of $1.00794g/mol$ and oxygen's atomic mass is $15.9994g/mol$.
There are two atoms of each element in hydrogen peroxide, so multiply these atomic masses by 2, and then add the products together.
$1.00794g/molx2=2.01588g/mol$
$15.9994g/molx2=31.9988g/mol$
When you add these products:
$2.01588g/mol+31.9988g/mol=34.01468g/mol$
