Too many unknowns in your question. Is this 3% by mass or by volume? Does the quantity of final solution matter? IE do you need 100 ml, 1 liter or 5000ml. What is the density of the hydrogen peroxide? (needed for a volume % problem)
Assuming you mean 3% by mass, then that means 3 g of hydrogen peroxide in 100 g of solution. 300 micromolar = 3 x 10-4 molar. Assuming you want to make one liter then you need 3 x 10-4 moles of peroxide. The molar mass of peroxide is 34 g/mole.
34 g/mole x 3 x 10-4 moles = 1.02 x 10-2 grams of peroxide
1.02 x 10-2 grams / .03 = 0.34 grams of the original solution.
Weigh (mass) accurately 0.34 g of the original solution in a 1 liter volumetric flask. Add distilled water until the total volume is 1 liter.

Is it necessary to know the formula of a compound in order to calculate its percent composition?
YES.For one to know the percentage composition,the amount of moles of the reacting element must be considered using the compound. •Well you dont really have to know just the formula. You can eaither use the formula if its given or the molar mass if its given. i just recently did a test where i was given either the Molar mass or Formula name and i had to figure out the percent composition. so it depends on the info given.
How do you make 600 mL of a 1 molar solution of HCl using a 6 molar stock solution?
combine 100 mL 6 M HCl with 500 mL H2O
Why didn't you need to know the molar absorptivity of the equilibrium mixture or the path length for the calculations you did in this experiment?
Simple. Because you have the percent transmittance (%T).Instead of using the Beer-Lambert Law:A=ϵbcyou use equation 7:A=2.00−log(%T)
What is the mass of 0.5623 moles of ethanol ch3ch2oh?
The molar mass of ethanol is 46g/mol. Using the formula mass = (molar mass) x (no. of moles), the mass of 0.5623mol of ethanol is approximately 25.9g.

Why are different masses of each element required to react with the same amount of hydrogen?
Each element has a different molar mass and Molarity, using stoichiometry the conversion of molar mass can explain why.
