Question

A compound contains 0.08% sulphur. The minimum
molecular mass of the compound is
(1) 10,000
(2) 20,000
(3) 35,000
(4) 40,000​

Answer 1

Answer:

4

Explanation:

in question ,asked minimum mol. mass of compound ,so sulphur will present in compound in minimum value of mole,i.e, = 1mole

1mole sulphur at.mass= 32 g

then,.

0.08%---------------------32g

1%--------------------------32/0.08=400g

100%-----------------------400×100=40000g

ans=40000g
