Answer:
The atomic mass of radon is 222.
Explanation:
. That means that one mole of radon weighs 222 grams (222 grams/moles). We can therefore make the following equation:
Grams × (1/222) = Moles of Radon
Answer:
Explanation:
(12 x 104 ) x (5 x 10-²) = 6 x 10 ³ 6 x 105 6.0x10²
1. (12 x 104 ) = 1248 or 1.248 x 10^3
2. (1.248 x 10^3)(5 x 10^-2) = 6.240 x 10^1 or 60 rounded to 1 sig fig
I don't understand "= 6 x 10 ³ 6 x 105 6.0x10² "
