Si la proporción en la que reaccionan el cobre y el azufre es: masa cobre/ masa de azufre =4:
a. ¿Qué masa de azufre reaccionará completamente con 4 g de cobre para obtener
monosulfuro de dicobre?
b. ¿Qué masa de sulfuro de cobre se obtiene?

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

idk what is it? is this a question that you know the answer or u dont

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.
