Consider the dissolution of cacl2: cacl2(s) > ca^(2+) (aq) + 2cl^(-1) (aq) deltah = -81.5kj
an 11.0 g sample of cacl2 is dissolved in 125 g water, with both substances at 25.0°c. calculate the final temperature of the solution assuming no heat loss to the surroundings and assuming the solution has a specific heat capacity of 4.18 j/c grams.

ans is no, the data set cannot be plotted as a single circle graph

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.
