Question

3. Show that the following data confirm the law of
multiple proportions :
(a) 1.77 g of metal oxide gives 1.61g metal on heating.
(b) 3.45g of metal oxide gives 3.21g metal on heating.
(C) 1.195g of metal oxide gives 1.04g metal on
heating.
​

Answer 1

Answer:

1.61 g of lead are combined with oxygen

g <br> 1.0 g of lead are combined with oxygen

<br> (ii) 6.42 g of lead are combined with oxygen

<br> 1.0 g of lead are combined with oxygen

<br> (iii) 1.035 g of lead are combined with oxygen

<br> 1.0 g of lead are combined with oxygen

<br> The ratio by mass of oxygen combining with 1.0 gram of lead in the three oxides is : <br>

<br> Since it is a simple whole number ratio, if illustrates the law of multiple proportions.
