Answer: z is 327g
Step-by-step 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
