Question

find volume occupied by 2.56g of gaseous sulphur molecule .​

Answer 1

Answer:

Volume = 224ml = 0.224 L

Explanation:

We know that,

Number of moles = Volume / 22.4

Number of moles = Given mass / Molar mass

Hence,

Volume / 22.4 = Given mass / Molar mass

Therefore,

Volume = (Given mass / Molar mass) * 22.4

Given that,

Given mass = 2.56g

Molar mass of sulphur molecule (S₈) = 32 * 8    (Mass of 1 sulphur atom = 32)

                                                             = 256g

Putting all these values in we get,

Volume = (2.56 / 256) * 22.4

Volume = 0.01 * 22.4

Volume = 0.224 Litre

Volume = 224ml
