Question

How many grams of H202 are in 3.50 moles of H202?

Answer 1

119.07 g/mol

Step-by-step explanation:

To calculate the grams of H₂O₂, first find the atomic mass using the periodic table.

H - 1.01 × 2 = 2.02

O - 16.00 × 2 = 32.00

2.02 + 32.00 = 34.02 g

Now to find the number of grams.

3.50 moles H₂O₂ × (34.02 g/1 mole H₂O₂) = 119.07 g/mol

Hope that helps.
