simple

yaar ye simple hai............. lekin mera answer match nai kar ra... asked in aieee. my one is 1.22
but given is 1.64 in g/ml

take care of 29%

?????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????

let density be d gm/lt.

then in 1000ml, mass of soln = d gm.

29% h2so4 so....

100gm soln has ... 29 gm h2so4

1gm has .............. 29/100 gm.

d gm has ...............29 d/ 100 gm

so, in 1000ml,

mass of h2so4, 0.29d gm.

now, mol mass = 98.

so, molarity = 0.29d/98X1000

= 3.60 (given)

=> d = 1.216

[i dun think its wrng... its a simple prob ... but its chem! so plz correct me if i am...
btw, aman, if u have taken this q from arihant ... it MAY have wrong ans :P ]

yeh sahi hai ki nahi ???
