Question

calculate the number of gram atom and gram molecule of sulphur in 8gram of sulphur. Atomic mass of sulphur is 32

Answer 1

Explanation:

gram atom basically means moles

so moles = given mass / molar mass = 8/32 = 0.25

Answer 2

Answer:

atomic mass of sulphur = 32 amu

one gram atom of sulphur = 32 g

now , 32 g of sulphur = 1 gram atom of sulphur

therefore 8 g of sulphur = 1/32 × 8

= 0.25 g of atoms of sulphur
