If your weight is 120 pounds and your mass is 54 kilograms how would those values change if you were on the moon? The gravitational force on the moon is 1/6 the gravitational force on Earth?

the question:
How many photons of wavelength 4.00 nm are required to heat 250.0 g of water from fuacet temperature of 10.6 C to 100.0C without boiling? asume all radiation is used to heat the water.

I figured that when it says by photons it meant waves becuase theres no equation which tells a number of photons. I first figured how much Kcals(1000 caloiries) were needed to heat the water, then how much Kcals where released through each 4.00nm wave of radiation. Then of course I divided them to figure out how many waves where need, but it came out to be an extremely small number.

My answer: 3.13 x (10 ^-3) , this answer i am not sure if i did it right like i could be wrong about how I came to solve it. I also redid it in Joules and came out to the same answer, but still it could be the way I did it.

So if you see a mistake in the way I did it, or show me how to do it, it would be helpful in my reveiw.

Maybe it's from the atomic weight? Maybe someone thinked of a formula stating that the atomic number came from the atomic weight with this formula:

Legend: A.W. is atomic weight while A.N. is atomic number.

A.W. (cancel all decimal places)
divided by:
2
= Atomic number.

I tried this, my own "experimental" formula whether it works. It worked accurately with oxygen and carbon, but in other elements, (try with krypton) it won't work. The quotient wasn't the atomic number in the Periodic Table of Elements, and I think the reason is that Krypton and other unequal A.N. elements belong in different groups are because they naturally need to be in a certain family or group. When I used the formula with krypton, it had the A.N. of 42, in the metals. Unfortuantely, krypton SHOULD belong to the non-metals.

I am searching for the truth if this formula is to be true. I have to prove this quick though, I need help in my never-ending researching. Thanks!

well i think that negative charge on carbon must be more stable as size of carbon is more as compared to oxygen resulting in lesser electron density that on oxygen !!!!!
