Empirical formula is the simplest ratio of whole numbers of components in a compound
calculating for 100 g of the compound
C H I
mass 3.05 g 0.26 g 96.69 g
number of moles 3.05 g / 12 g/mol 0.26 g / 1 g/mol 96.69 g / 127 g/mol
= 0.254 mol = 0.26 mol = 0.7613 mol
divide by the least number of moles
0.254/ 0.254 = 1.0 0.26 / 0.254 = 1.0 0.7613 / 0.254 = 2.99
when rounded off
C - 1
H - 1
I - 3
empirical formula is CHI₃
answer 1) CHI₃
Answer:
112.18 g.
Explanation:
you're using stoichiometry to find the mass of the compound S₃O.
Answer:
pH = 3; acidic
Explanation:
The equation to find pH given [H+] is:
pH = -log[H+]
In the question it gives us the concentration of [H+], which is 0.0010 M.
Now just plug this into the equation to solve:
pH = -log(0.0010)
pH = 3
This would make the solution acidic as it is less than 7.
Hope this helps!!
