Question

convert into moles. 1) 12g of oxygen gas​

Answer 1

Answer:

Answer is : 0.375 moles

Explanation:

oxygen= O2 = 16×2=32

therefore molar Mass of oxygen=32

n=M/m

no of moles = given mass/molar Mass

n=12/32

n= 3/8

when divided answer is 0.375

Answer 2

Answer:

MOLECULAR MASS OF O²=32U

Mass of O²=12g

No. of moles of O²= mass/ molecular mass

=12/32=3/8

=0.375 moles
