A `3.42%` (wt.`//`vol.) solution of cane sugar is isotomic with a `5.96%` (wt.`//`vol.) solution of raffinose. The molecular weight of raffinose is:

Options

A. 59.6
B. 596
C. 5.96
D. 5960

Answer

B

Explanation

For two non-electrolytic solution, `C_(1) = C_(2)`.
`(W_(1) xx 1000)/(M_(1) xx 1000)=(W_(2) xx 1000)/(M_(2) xx 1000)`
`:. (3.42 xx 1000)/(342 xx 1000)=(5.96 xx 1000)/(M_(2) xx 1000)`
`:. M_(2) =596`
