Answer:
4.13×10^22 atoms
Explanation:
1. Find number of moles
mole=mass/rmm of compound
mole= 3.50/102
mole= 7/204 mol
2. Multiply it with avagadros constant( 6.02×10^23 particles)
7/204 × 6.02×10^23= 2.0657×10^22
3. Multiply it with the number of ALMINIUM ATOMS IN AL203( which is 2 atoms)
2.0657×10^22 × 2
you get 4.13×10^22 atoms
Answer: A=12
Explanation:
4.5
The amount of chemical remaining after twelve seconds in the first reaction is:
A = 12 - 0.5(12)
= 12 - (6)
= 6
In the dissolved reaction, the amount of chemical loses half of itself every four seconds. This is the same thing as dividing by 2 every four seconds.
This is an exponential decay, so the amount of chemical divides by 4 every eight seconds, and by 8 seconds every twelve seconds. The amount remaining after twelve seconds in the second reaction is:
A' = 12/8
= 3/2
= 1.5
The difference between the amounts of chemical remaining is:
6 - 1.5 = 4.5
Therefore, A is 4.5 g greater than A' after twelve seconds.
Density = mass/volume. 5000/50= 100 grams per cubic centimeter. No substance on Earth has anywhere near that density. Tops is about 20 for osmium and gold.
