0.07cm³
Explanation:
Given parameters:
Density of the body = 350g/cm³
Mass of the body = 25g
Unknown:
Volume of the body = ?
Solution:
Density is the amount of substance contained in a volume of body. It is expressed as:
Density =
Since the unknown is volume, we make it the subject of the expression;
Volume =
Volume = = 0.07cm³

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>
