Answer to Question #113095 in General Chemistry for Salman Cheema

Question

calculate the mass of hcl in grams when 250cm3 of water is added to 100cm3 of 0.5M hcl

Answer 1

$M1\times V1=M2\times V2$

$0.5\times0.1=M2\times0.35$

$0.05=M2\times0.35$

M2=0.14

$n=M\times V=0.14\times0.35=0.05$

$m=n\times M=0.05\times36.4610=1.82$ g
