If we are given the mass of one substance, we can calculate volume of other substances and vice a versa with the help of balanced chemical equation. This is called:
Correct answer: D. Mass-volume relationship
- A. Mass-mass relationship
- B. Mass-mole relationship
- C. Mole-volume relationship
- D. Mass-volume relationship
Explanation
A is incorrect as mass-mass relationship involves converting the mass of a reactant to moles of reactant, then using mole ratios to determine moles of product which can then be converted to mass of productB is incorrect as mass-mole relationship refers to finding moles of a substance using its mass.C is incorrect as a mole-volume relationship refers to finding volume of a substance using its moles.D is correct as mass-volume relationship refers to finding volume of a substance using its mass.mass of given → moles of given → moles of unknown → volume of unknown

About Moles and Avogadro's Number
The mole connects the microscopic number of particles with measurable mass, using Avogadro's number, 6.022 × 10²³ particles per mole. Questions involve molar mass, conversion between mass, moles and particles, percentage composition, empirical and molecular formulas, and distinguishing atoms, molecules, ions and formula units.
