2. What is the empirical formula of a compound composed d of 3.26 g of arsenic and I .04 g of oxygen?

## Step 1The empirical formula compound is the simplest whole number ratio of atoms of each element in the compound. To find the empirical formula, we first need to convert the given masses of each element to moles. This is done by dividing the mass of each element by its atomic mass.### **Moles = **## Step 2The atomic mass of arsenic (As) is approximately 74.92 g/mol, and the atomic mass of oxygen (O) is approximately 16.00 g/mol.## Step 3Calculate the moles of arsenic and oxygen:### **Moles of As = **### **Moles of O = **## Step 4The ratio of moles of arsenic to oxygen is then calculated.### **Ratio = **## Step 5The ratio is approximately 1:1, which means the empirical formula of the compound is AsO.
