Problem: Vanadium forms four different oxides in which the percent by mass of vanadium is respectively 76 % , 68 % , 61 % , and 56 % .Find the formula of the first oxide.

FREE Expert Solution

Step 1 Assuming 100 g, V is 76 g and O is 24 g

= 1.49 mol V

= 1.5 mol O

Step 2 Divide each mol by the least moles

= 1 V

= 1 O
