What is the molality of a solution in which 0.145 mol carbon dioxide is dissolved in 591 kg water?

it's c. elements are placed in rows based on how may valencies electrons have.

12 is it do you think so

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.
