Amina observed that crystals of copper sulphate are formed in the solution, when a 3 saturated solution of copper sulphate has cooled. Will the solution be still remained as saturated? Why?

answer: mole of the gas

answer: mole of the gasexplanation:

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
