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

###### FREE Expert Solution

We’re being asked to determine the name of the first oxide of a compound composed of V and O, given the mass percent of O.

Recall that the empirical formula is the simplest whole-number ratio formula of a compound

For this problem, we need to do the following steps:

Step 1: Calculate the mass and moles of V and O in the compound.

Step 2: Determine the lowest whole number ratio of V and O to get the empirical formula.

Step 3: Determine the name of the first oxide.
