0.8g and 1.5g of two metals oxides were found countain 0.64g and 1.2g of metal respectively. show that this results obey law of definite proportion

Respuesta :

Answer

This obey the law of definite proportion

Step-by-step explanation:

The Law of definite proportion states that any chemical compound will always contain a fixed ratio of elements by mass

According to the question,

Let the first oxide = x

Let the second oxide = y

x = 0.8g

y = 1.5g

For the first metal oxide, the amount of metal is 0.64 grams

Hence, the mass of oxygen is (0.8 - 0.64)

Mass of oxygen = 0.16g

Mass ratio = Mass of metal/mass of oxygen

Mass ratio = 0.64 / 0.16

Mass ratio = 4 : 1

For the second metal oxide, the amount of metal is 1.2g

Amount of oxygen = (1.5 - 1.2)

Mass of oxygen = 0.3

Mass of oxygen = 0.3g

Mass ratio = mass of metal/mass of oxygen

Mass ratio = 1.2 / 0.3

Mass ratio = 4: 1

Hence, the ratio of metals to oxygen is in the ratio of 4 to 1

Answer

Hence, this obey the law of definite proportion
