Question

11.2 litre of oxygen at STP contains the same number of molecules as 24 grams of aother substance the molecular weight of the substances​

Answer 1

Answer:

may be 48 is molecular weight of the substance

Explanation:

because oxygen contains 22.4 L volume for one mole. for one mole number of molecules are equal to Avogadro's number (6.022 X 10²³)

given volume of oxygen is 11.2 L hence number of moles should be 0.5

Given substance weight is 24 g so if molecular weight is 48 its number of moles are 0.5

moles = weight/molecular weight
