Which of the following contains the most atoms: A. 1 mol of SF6
B. 1 mol of HCl
C. 1 mol of CH3CH2OH
D. 1 mol of B2F4
E. all contain the same number of atoms

if you're asking what comes out, it's steam.

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.
