A sealed balloon is filled with 1.00 L helium at 23 °C and 1.00 atm. The balloon rises to a point in the atmosphere where the pressure is 225 torr and the temperature is -31 °C. What is the change in volume of the balloon?

the answer would be a

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.
