What is the relationship between a mole and Avogadro number
2 answers:
Answer : The relationship between a mole and the Avogadro number is, 1 mole of a substance contains number of atoms, molecules or ions.
Explanation :
Mole : It is defined as the amount of substance that contain the same number of units as there are atoms present in exactly 12 grams of carbon-12.
Avogadro's number : It is defined as the number of atoms molecules present in a mole of any substance.
The Avogadro's number is represented as,
The relationship between a mole and Avogadro number are,
As, 1 mole of a substance contains number of atoms, molecules or ions.

Answer:
In which [Ag+] in negligibly small and the concentration of each reactant is 1.0 M
The answer is A) PO43- < NO3- < Na+
Explanation:
Ag+ is removed from the solution just like PO43-, so there are just 2 possible answers at this point: a or b. Then we can notice that Na3PO4 releases 3 moles of Na+ and just 1 mole of NO3-
We have 100mL of each reactant with the same concentration for both (1.0 M) so:
(0.1)(1)(3)= 0.3 mol Na+
(0.1)(1)= 0.1 mol NO3-
so PO43- < NO3- < Na+
Answer:
n = 12.18 moles
Explanation:
Given that,
The volume of a canister, V = 1 L
The temperature of the canister, T = 100 K
Pressure, P = 100 atm
We need to find the number of moles of gas. Let there are n number of moles. We know that,
PV = nRT
Where
R is gas constant, R = 0.0821 L*atm/mol*K
Hence, there are 12.18 moles of gas.
