Answer:
Theoretical yield of vanadium = 1.6 moles
Explanation:
Moles of = 1.0 moles
Moles of = 4.0 moles
According to the given reaction:-
1 mole of react with 5 moles of
Moles of Ca available = 4.0 moles
Limiting reagent is the one which is present in small amount. Thus, Ca is limiting reagent. (4.0 < 5)
The formation of the product is governed by the limiting reagent. So,
5 moles of Ca on reaction forms 2 moles of V
1 mole of Ca on reaction for 2/5 mole of V
4.0 mole of Ca on reaction for mole of V
Moles of V = 1.6 moles
<u>Theoretical yield of vanadium = 1.6 moles</u>
Answer:
<h2>Density = 0.00026 g/mL</h2>Explanation:
The density of a substance can be found by using the formula
<h3>From the question
mass of air = 1.2 g
volume = 4,555 mL
Substitute the values into the above formula and solve for the density
That's
<h3>= 0.0002634
We have the final answer as
<h3>Density = 0.00026 g/mL</h3>Hope this helps you
