Answer:
= 4.37*10^-9 M
Explanation:
We know that;
pH + pOH = 14
Therefore;
pH = 14 - pOH
Which means; pH = 14 - 5.64
= 8.36
But;
pH = -log[H3O+]
Thus;
8.36 = -log[H3O+]
[H3O+] = 10^(-8.36)
= 4.37*10^-9 M

Explanation:
<em>hope it helps :))</em>
Explanation:
“The isomers butane and methyl propane have the same molecular formula and different properties”, this is because structural isomers usually have different properties to their parent.
The average atomic mass if the element above is calculated by the sum of the product of the isotope abundance and its atomic mass unit. It is expressed as:
Average atomic mass = Σ xi(Mi)
<span>Average atomic mass = (.7547 x 248.7) + (.2453 x 249.4) = 248.87

Hope this helps.
