Question

You have 1.29 moles of hydrogen peroxide, H2O2. How many grams is this?

Answer 1

Answer:

m = 43.87 grams

Explanation:

Given that,

Number of moles, n = 1.29 moles

The molar mass of H₂O₂ is, M = 34.0147 g/mol

We know that,

$n=\dfrac{m}{M}$

Where

m is mass of H₂O₂

So,

$m=n\times M\\\\m=1.29\times 34.0147 \\\\m=43.87\ g$

So, there are 43.87 grams of H₂O₂.
