A wood block measures 3cm in length, 4cm in width, and 5cm in height. The block has a mass of 180 grams. What is the block's density?

Finding volume:

V(wood)=l×b×h=3×4×5=60cm³

we have been given the mass of the wood as 180 grams and we know that"

Density = mass/ volume

substituting in the mass and volume

=> D=180/60=3g/cm³

 The  best    reason  for the  difference  in  properties of LiCl  and C6H14O is

one  compound  is a covalent  and  the other is ionic

Explanation

 LiCl  is ionic  compound while C6H14O  is  a   covalent   compound.

Ionic compound   is formed  when  a  metal  and   non metal  react.  Metal  donate electrons( loses electrons)  while  non   metal   except gain ( gain  electrons).

LiCl is  ionic  compound since Li  loses  1 electron while  Cl  gain that   1 electron  to  form  ionic compound.

Covalent  compound  is formed  when    non  metal react  by  sharing electrons.
