What is the empirical formula
**Problem 1: Determining the Empirical Formula** A sample of a salt composed of nickel and phosphorus contains 2.348 grams of nickel metal and 0.827 grams of phosphorus. Determine the empirical formula of the salt. **Solution Steps:** 1. **Convert Mass to Moles:** - Calculate the moles of nickel (Ni) by dividing by its molar mass. - Calculate the moles of phosphorus (P) by dividing by its molar mass. 2. **Determine the Mole Ratio:** - Divide the moles of each element by the smallest number of moles obtained in the previous step. 3. **Write the Empirical Formula:** - Use the mole ratio to assign subscripts to each element in the chemical formula. This problem involves understanding the concept of empirical formulas and how to derive them from given masses of elements in a compound.
