no
1 kg = 1000 grams
1 gram = .001 kg
Yes, 2200 g is equal to 2.2 kg.
Yes, it is
1kg = 1000g so 3kg = 3000g, which is less than 3241g
No
500 grams = 0.5 kilograms < 2 kilograms
no
Yes
1 kg = 2.20462 pounds 222 kg x 2.20462 pounds/kg = 489.4 pounds The formula to convert kg to lbs 222 kg* 2.2046 lbs 1 kg = 489.4262221 lbs you may try the online converter linked below
Rn-222 emits alpha radiation.
The equation for the alpha decay of radon-222 takes the following form. Radon-222 ----> He + Polonium. In an alpha decay, the atom loses 2 neutrons and 2 protons.
I will give 1/3 of the answer to these questions; and 1/3 is better than nothing! Avogadro's Law is simple and I will give it in terms to which it is used to solve chemistry and radioactivity problems. Just like advance calculus, by using a calculational example, this will succinctly give the law its most powerful meaning. Avogadro's number is all you need to know, and all you will ever need to know. The Law simply states that for every mole of an element (in the Periodic Table) there is present exactly 6.02 x 10^23 atoms. What do you do with this? Well, for example, take a radioactive element such as Rn-222. The 222 refers to the atomic mass of the radionuclide. From that you can crank out the following: (222 g/mole)/(6.02 x 10^23 atoms/mole) to get a grams/atom answer, or how much mass is in one atom of radon-222. This is important in calculating radiation dose problems and in other chemistry problems. Remember, the atomic mass of the element can be given the units of grams (g) per mole. The mole is a simply a unit defined as having that many atoms (Avogrado's number). That all! Now you know the inner mystery of what Avogadro's Law (and number) means and how it specifically applies to solving all P-Chem problems. And all this was done without resorting to abstruse terminology!

111 is 111 fewer than 222.
222 is more than 100 times larger than 2.20462.
It is: 2461
No. Think of it like this. 0.222's fraction form is 222/1000 and 0.25's fraction form is 25/100. To compare, you need to make them the same denominator. So 25/100 turns into 250/1000. Now what is bigger 222/1000 or 250/1000?
Less than because when you multiply 6 cereal bars by 37 g./bar you get 222 g. Convert 222 g. to kg and it is .222 kg.
The atomic number of radon (Rn) is 86. The atomic weight of Rn is 222 grams per mole.
222 plus 222 equals 444.
