Which quantity will correctly convert between two different substances

molar mass
molar ratio
avogadro's number
chemical reaction

Molar ratio is the quantity which will correctly convert between two different substances.

Option B

Explanation:

Molar ratio is used to determine the number of moles of reactants required to convert to desired number of moles of the products and vice versa. As moles are the coefficient written in any chemical equation. The ratio of the number of moles of the reactants to the number of moles of the products will help to determine the molar ratio.

This molar ratio is used as the conversion factor to determine number of moles required in the reactant side for the reactants to form a desired product of desired moles. We can also determine the number of moles utilized from the reactants from the moles obtained in the products using this molar ratio conversion factor.

warm front forms when a moist, warm air mass slides up and over a cold air mass. as the warm air mass rises, it condenses into a broad area of clouds. a warm front brings gentle rain or light snow, followed by warmer, milder weather.
