Answer:
78 : 71
Explanation:
From the question given above, the following data were obtained:
Mass of KCl = 149 g
Mass of K = 78 g
Mass ratio of K and Cl =?
Next, we shall determine the mass of Cl in the compound. This can be obtained as follow:
Mass of KCl = 149 g
Mass of K = 78 g
Mass of Cl =?
Mass of Cl = (Mass of KCl) – (Mass of K)
Mass of Cl = 149 – 78
Mass of Cl = 71 g
Finally, we shall determine the mass ratio of K and Cl. This can be obtained as follow:
Mass of K = 78 g
Mass of Cl = 71 g
Mass ratio of K and Cl =?
Mass ratio = mass of K / mass of Cl
Mass ratio = 78 / 71
Therefore, potassium, K and chlorine, Cl are released in mass ratio of 78 : 71
