• # question_answer 'a' gm of element A reacts with 'b' gm of element B. Also 'b' gm of element B combines with 2c gm of C. If one gm equivalent of B weighs 'b' gm. Then the mass ratio in which A and C combine is A)  $a:c$              B)  $a:2c$C)  $2a:c$                        D)  $3a:c$

$1\,gm$equivalent of B reacts with $1\,gm$ equivalent (i.e., ?a? gm ) of A $1\,gm$ equivalent of B will also react with $1\,gm$equivalent (i.e. $2c\,gm$) of C. Therefore, ratio of gm equivalents of A and C is a : 2c
