Calculation of apparent density of stone Take the dry stone with mass of M (unit: G) and saturate it with water, then put it into the jar, fill it with water and try to exhaust the air, and then close the bottle mouth with glass sheet to get the total mass of M1. Then pour the stone and water out of the jar, fill the bottle with water, and then close the bottle mouth with glass sheet to get the mass of M2. Let the water density be ρ w (unit: g / cm3), What's the apparent density of stones? Which master can explain this problem clearly? It's better to be more detailed,

ρ=[m/(m+m2-m1)]*ρw
That's how it works
