Answer: 3.5 moles V2O5
Explanation: First balance the chemical equation to find the stoichiometric factor between VOCl3 and V2O5
2 V2O5 + 6 Cl2 => 4 VOCl3 + 7 O2
So the mole to mole ratio is 2 moles V2O5 to 4 moles of VOCl3
Solution
7 moles VOCl3 x 2 moles V2O5 / 4 moles VOCl3 = 3.5 moles V2O5
Answer:
70 amu
Explanation:
The average atomic mass of an element is calculated by first finding the products of the atomic masses of the isotopes of that element and their respective percent abundances. The second/last step is finding the sum of those products, applying significant figures rules throughout. In this case, you would do the following:
(69 x 60%) + (71 x 40%) = 70 amu (with significant figures rules applied)

The scientist could B) do an experiment to that would apply to only one of the theories.
If the results agreed with that theory, it would <em>become more acceptable</em>.
If the results disagreed with that theory, it would be <em>disproved</em> and the other theory would become more acceptable.
