If another proton gets added to the molecule there will be an increase in the atomic number and atomic mass by 1 unit and a new species will form.
here boron is taken which has an atomic number of 5 and atomic mass of 11 so when we add a proton to it, it will change into carbon having atomic number as 6 and atomic mass as 12.
The new species formed will be .
Answer:
1.99 x 10²³ formula units
Explanation:
Given parameters:
Mass of AgF = 42.15g
Unknown:
The amount of formula units
Solution:
To solve this problem, we set out by find the number of moles in this compound from the given mass.
Number of moles =
molar mass of AgF = 107.9 + 19 = 126.9g/mol
Number of moles = = 0.33 moles
1 mole of a substance = 6.02 x 10²³ formula units
0.33 moles of AgF = 0.33 x 6.02 x 10²³ = 1.99 x 10²³ formula units
