Hello, I need help studying for a chemistry test out could someone please help get the baseline down for some of these prompts so I have a template to expand off of. 1.Using experimental data, determine the relative mass of two objects

2.Use experimental data to determine the number of particles in a sample without counting them individually

3. Given a chemical formula, determine its molar mass be able to calculate mass, mole, or number of particles from any one of mass, mole, or number of particles.

4. Given a chemical formula, be able to calculate the percent composition for that substance.

5. Given percent composition data, be able to calculate the empirical formula for a substance.

6. Given percent composition data and molar mass, be able to determine the molecular formula for a substance.
