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
A. Strong acids have a high ionization.
Answer is: 4)Mass
I really hope this helped you out!!!!
Answer:
A. 14/15
B. 17/14
C. 5/12
Explanation:
Convert all so that the denominators are the same.
A. 3/5 + 1/3 = 9/15 + 5/15 = 14/15
B. 5/7 + 1/2 = 10/14 + 7/14 = 17/14
C. 1/6 + 2/8 = 4/24 + 6/24 = 10/24 = 5/12
I think the answer would be Ga3+
