X=124 grams y=49 z=? The product weighs 500 grams what is the mass of z

z is 327g

Explanation:

Given that,

Mass of X=124 grams

Mass of y = 49 grams

Mass of z = ?

Since the product weighs 500 grams, then X, y and z are reacted as follows:

X + y + z ---> products

So, 124g + 49g + z = 500g

173g + z = 500g

z = 500g - 173g

z = 327g

Thus, the mass of z is 327g

it is stable as it is in group 0 which have full outer shells of electrons

answer; 4 electrons;
