You can cross multiply and then get k alone so it would look like this:
76 81
----- = ------ = 76k= 24624
304 k ----- ----------- = k = 324
76 76
so k is equal to 324
hope this helps have a nice day
Answer:
Mass of AgI formed=0.352g
Explanation:
AgNO3 + NaI ----‐>AgI + NaNO3
Volume of AgNO3 =5g/L
Mass of AgNO3 =C×V=0.25g
n(AgNO3)= m/Mr=0.0015mol
For NaI
V= 5g/l
Mass= C×v=0.25g
n=m/Mr=0.0017mol
n=0.0015mol
Mass=n× mr=0.352g

Answer:
C. the relative molecular mass of the compound
Explanation:
Like molecular formulas, empirical formulas are not unique and can describe a number of different chemical structures or isomers. <u>To determine an empirical formula, the relative molecular mass of the composition of its elements</u> can be used to mathematically determine their ratio.
