How can a scientist make a solution using salt and water?

by boiling water and add the salt

Explanation:

because salt dissolves better if mixed with hot water which makes the process faster and effective

the answer is c i took the test

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.
