Mass of Calcium phosphate : = 21127.7 g
<h3>Further explanation</h3>
Given
4.1 x 10²⁵ particles of Calcium phosphate
Required
mass
Solution
The mole is the number of particles(molecules, atoms, ions) contained in a substance
1 mol = 6.02.10²³ particles
Can be formulated
N=n x No
N = number of particles
n = mol
No = Avogadro's = 6.02.10²³
mol Calcium phosphate :
n = N : No
n = 4.1 x 10²⁵ : 6.02 x 10²³
n = 68.11
mass Calcium phosphate Ca3(PO4)2 :
= mol x MW
= 68.11 x 310.2 g/mol
= 21127.7 g
= 21.13 kg
Answer:
-3, 34, 34, 9
Explanation:
charge = number of electrons - number of protons
mass number = number of protons + number of neutrons
number of protons = number of electrons
atomic number = number of protons
Alrighty, so, imagine you didn't or don't know much about desertification. You could imagine that it means the land becomes a desert. Knowing this I think it's easy to assume that desertification makes it harder for people in Southeast Asia to grow food or even build houses once their natural resources are destroyed from desertification.
