6. Haydee prepared a solution with 3mL of potassium chloride (KCl) in 200 mL of water is prepared. Calculate the percent by volume concentration of the solution. A. 1.46% B.1.48 %
C. 1.49 % D. 1.50%

the correct answer is:

a. formation of precipitation

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.
