w2=98 g , w1=100 g , d=1 . 8 g mL Volume of solution =( text Mass / text Density )=(100/1 ⋅ 8)=55 . 55 ML Molarity =( w 2 × 1000/ M 2 × V ( in mL )) =(98 × 1000/98 × 55.55)=18 M Now, M1 V1=M2 V2 18 × V1=0.1 × 1000 ⇒ V1=(0.1 × 1000/18)=5.55 mL

Q. Concentrated aqueous sulphuric acid is 98%H2​SO4​ by mass and has a density of 1.80g.mL−1 Volume of acid required to make 1 litre of 0.1MH2​SO4​ solution is:

11.10 mL

5.55 mL

16.65 mL

22.20 mL

w2​=98g,w1​=100g,d=1.8gmL Volume of solution = Density Mass ​=1⋅8100​=55.55ML Molarity =M2​×V(inmL)w2​×1000​ =98×55.5598×1000​=18M Now, M1​V1​=M2​V2​ 18×V1​=0.1×1000 ⇒V1​=180.1×1000​=5.55mL
