We know that a. $Molar \space mass \space of\space CSI=259$ Hence $Mass=0.025\times 259=6.5g$ b. $Molar \space mass\space of H_2SO_4=98$ $Mass=0.025\times 98=2.44g$ c. $Molar\space mass \space of Na_2CO_3=106$ $Mass=0.025\times 106=2.65g$ d. $Molar \space mass \space of K_2Cr_2O_7=294$ $Mass=0.025\times 294=7.35g$ e. $Molar\space mass \space of KmNO_4=158$ $Mass=0.025\times 158=3.94g$
