9.) loss of wt = wt of displaced water = 2
Let the amt of cu = x
So,
36 - x / 19.3 + x / 8.9 = 2
Solving this we get 10.4 x = 343.54 - 320.4
so x = 2.225 gms
 
 
Next one take volume as a variable and find out the answer its simple

From J.R.R. Tolkien's 'The Lord of the Rings':

All that is gold does not glitter
Not all who wander are lost
The old that is strong does not wither,
Deep roots are not reached by frost.
From ashes a fire shall be woken
From shadows a light shall spring
Renewed shall be blade that's broken
The crown less again shall be king.
