Simplified Version of the Law of Definite Proportions is that
Always contains exactly the same proportion (ratio) of elements by mass.
Who created the Law of Multiple Proportions?
John Dalton
Law of Multiple Proportions is the ____
“the ratio of masses of one element that combine with a constant mass of another element can be
expressed in small whole numbers”.
Simplified Version of the Law of Multiple Proportions is that
simplifying a ratio to a whole number
