The mass of 50% (mass/mass) solution of HCI required to react with 100

1.	The mass of 50% (mass/mass) solution of HCI required to react with 100g of CaCO_3would be
Answer» 73 g 100 g 146 g 200 g Solution : eq of HCI = eq of `CaCO_3` `W/(36.5) =100/50 , W_(" HCI") = 73` gam 50 g of HCLIS present in 100GM of HCI solution 73g of HCI `rarr "?"`= 146 gmof HCl
