A sample of oxygen gas occupies a volume of 250mL at a pressure of 1.25 atm. What volume will the gas occupy at a pressure of 2.50 atm if temperature is held constant?

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.
