Assuming the density of 3% h2o2 is 1.00g/ml, what mass of h2o2 is in a 1.00ml sample? how many moles is this ?

Mass of H2O2 = 0.03 g

Moles of H2O2 is 8.82*10^4 (approximately 9.0*10^-4 moles)

Explanation:

Given:

Concentration of H2O2 = 3%

Volume = 1.00 ml

Density = 1.00 g/ml

To determine:

Mass and moles of H2O2 in the given sample

Calculation:

Here, 3% H2O2 implies that there is 3 g H2O2 in 100 ml of sample

Therefore, amount of H2O2 in 1.00 ml sample would be:

Molecular weight of H2O2 = 34.01 g/mol
