When a sample of a gas was placed in a sealed container with a volume of
5.35 L and heated to 105 degrees Celsius, the gas vaporized and the
resulting pressure inside the container was 180.0 kPa. How many moles of
the gas was present?

a. 0.110 mol
b. 0.205 mol
c. 0.306 mol

d. 1.10 mol

c-14 is carbon-14, or radiocarbon.   it is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons.

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.
