The fragrant organic compounds found in many flowers that contain a carbonyl group bonded to a carbon atom and a hydrogen atom are called aldehydes.
To find density, you just divide the mass by the volume (density is the measurement of the amount of mass in a certain volume):
___3% H2O2 (mass/vol)
<span>a) mass bought = 3g/100ml * 250 ml = ?? g H2O2 </span>
<span>b) moles / 0.250 liter = (?? g H2O2 / MW H2O2 g/mole) / 0.250 liter = ??M </span>
<span>Plug and SOLVE </span>
<span>Basic mathematics is a prerequisite to chemistry – I just try to help you with the methodology of solving the problem.

Idk I think its a major addation Or Reading Or Socail Studies Sorry tho
