Calculate the pH of a solution formed by mixing 200.0 mL of 0.300 M NaHSO4 with 200.0 mL of 0.200 M Na2SO4 and 1.0 ml 1.00 M NaOH. The Ka2 for H2SO4 is 1.2 × 10-2.

personal, she chose to do it.

your answer is c) plasma

~*"auba14"*~

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.
