How many particles are in a 172 g sample of Cu2O3? A: 5.89 x 1023 particles Cu2O3
B: 5.03 x 1023 particles Cu2O3
C: 5.03 x 1024 particles Cu2O3
D: 5.89 x 1024 particles Cu2O3

the answer is the

it would be b. 6co2 + 6h2o --> c6h12o6 + 6o2

i think its 100.

hope this !

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.
