Lesson: Applying Mathematical Skills Chemistry
In this lesson, we will learn how to apply various mathematical skills to determine values and solve problems in a chemistry context.
A molecule of ammonia consists of atoms of nitrogen and hydrogen in a 1:3 ratio. A sample of ammonia contains 6 atoms of nitrogen. How many atoms of hydrogen does it contain?
An atom of an isotope of tin has an electron-to-proton-to-neutron ratio of . If the atom of the tin isotope has 50 protons, how many neutrons does it have?
An experiment determines that for every 500 collisions between two atoms, only 30 successfully result in the formation of 30 molecules. If there are 200 collisions, how many molecules are formed?
