WebMar 24, 2024 · To calculate the mass of an object, use the formula d=m/v, where d is density, m is mass, and v is volume. So, if the density of the object is 500 kilograms per … WebIn the first case you'd have to find one way of separating the two chemicals containing potassium. Then after measuring their individual masses the calculation becomes similar to what Sal did. The second case you'd have to separate potassium containing chemical from the rest of the supplement.
How is the mass of the Earth determined?
Web1 Answer Sorted by: 3 That works! In most chemistry (but not nuclear reactions!), mass is always conserved, so m solution = m solvent + m solutes Mass is also equal to density times volume, so m solution = ρ solution V solution = m solvent + m solutes Solving for m solvent: m solvent = ρ solution V solution − m solutes WebMar 10, 2024 · Measuring Mass with a Balance 1.
