Question No. 1
Percentage of weight by volume of 0.6 M AgNO3(aq) (molar mass of AgNO3 - 170 g/mol) is
(A)
17%
10.296
O
10.2%
5.1%​

Answer 1

Answer:

Explanation: I think it's 10.2%

Answer 2

Answer:

10.2 %

Explanation:

Molarity =( no. of moles/vol. In ml )

0.6 M of agno3 means that 0.6 mole of agno3 is present in 1 litre i.e. 1000ml of water.

Hence, weight of agno3 = no.of moles× molarmass = 0.6× 170=17×6=102g

Now,

Percentage of weight by volume = (weight/volume in ml)×100

=(102/1000)×100

=10.2%

Hope it helps....
