What is the molarity of a solution made by adding 1.565 moles of PbNO3 to 500 mL

fe 55.85 g/mol and h2o 18.02 g/mol.

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.
