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>
The chemical formula depends on the type of acids it is. Acidic rain is a complex mixture of nitrous, nitric, sulfurous and sulfuric acids which all combine to lower the pH.
The number 250 mg tablets of Metronidazole that are needed to make 150 ml of suspension containing 100 mg/ml
250mg= 150 ml
what about 100 ml = ? Mg
by cross multiplication
150 ml x 250 mg/100 ml = 60 Mg of 250 mg is needed
