Measure the diameter. Calculate the volume, V = 4/3 Pixr^3. Calculate the mass of air from the ideal gas law PV = nRT. Assume air to be 20% oxygen and 80% nitrogen.

Weigh the empty condom. Then fill it with air and seal it (I'm not sure how you'd seal it though). Weigh the condom with the air in it. The difference between the first and second weighing will be the weight of the air.

If you're using a clamp or string to seal the condom, weigh that when you weigh the empty condom and factor it in (though if it's string the weight difference would be negligible).

Air inside the condom and outside the condom will weigh the same. So if you were to put a flat condom on scales and weigh it, it would weigh the air around it and you'd get one answer. Then if you put air into the condom and weigh it, you will get the same answer. The air has merely transfered from outside the condom to inside the condom. Both locations for air will be "on the scales", so to speak.

Does that make sense?

what exactly do they teach in science these days, does a condom need to be fully filled with air. Tell your teacher to stop being a perv and find some real work for everyone to do.

Bits and pieces of the answer have been given:
> blow up the condom
> seal
> allow condom to reach room temperature
> use submersion in room temperature water to determine volume
> air density at room temperature is 1.225 kg/m^3

i'm uncertain which fact via the Pope you're relating, so i'm no longer able to reply to his particular words. yet i will make a guess that he probable had some factor to declare against condoms and their utilization. to sentence using something on no account means that it extremely is "unscientific" or the information approximately it are incorrect. If i desire to advise that persons no longer consume arsenic because of the fact it extremely is risky for them, i'm no longer denying any of the clinical evidence approximately arsenic. in simple terms on the grounds which you have a different opinion with reference to using condoms that does the Pope, that does no longer make his opinion conflict with "technology".

"Air" weighs nothing because it is a function of gravity. But the mass of the air, thats a different story.

Weigh it before and after you blow it up. Then the difference will be the weight of the air.

Your teacher should be reported to the Board of Governors
