The process of mineral formation from magma is called melting crystallization evaporation precipitation

okay here is my  answer and explanation

The process of mineral formation from magma is called crystallization. Molten rock has a specific chemical composition, which determines what minerals crystallize when the molten rock cools. Magma cools slowly underground, which allows large mineral crystals to grow.

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.
