If an atom of Phosphorous has 17 neutrons, what is its mass number? a) 31
b) 32
c) 15
D) 17

the temperature of the gas, in k, not celsius.

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.

answerleaving cheese out to get moldy;

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.
