What volume will 0.250 mol of O2 occupy at 45.0oC and 2.00atm?

explanation:

answer; the numbers of valence electrons in the acetic acid molecule (ch3co2h) is 24;

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.
