Law of Multiple Proportions Video Lessons

Concept: Law of Multiple Proportions

# Problem: Hydrazine, ammonia, and hydrogen azide all contain only nitrogen and hydrogen. The mass of hydrogen that combines with 1.00 g of nitrogen for each compound is 1.44x 10-1 g, 2.16 x 10-1 g, and 2.40 x 10-2 g, respectively. Show how these data illustrate the law of multiple proportions.

###### FREE Expert Solution

We’re being asked to find the formula of an oxide of carbon in which the ratio by mass of oxygen to carbon is 2.00:1.00.

We’re given the ratio of oxygen (O) to carbon (C) by mass in carbon monoxide is 1.33:1.00.

According to the Law of Multiple Proportions, when two elements (A & B) form different compounds, the masses of element B that combine with 1 g of A are a ratio of whole numbers.
