Perimeter Institute is hosting its fourth Inspiring Future Women in Science conference on Thursday, March 23, 2017 from 9:00 am – noon. The conference brings together like-minded young women who have a strong interest in pursuing science as a career path and are currently enrolled in high school. The conference is designed to provide female high school students with opportunity to interact with STEM professionals through keynotes, panel discussions, and mentoring. //www.perimeterinstitute.ca/outreach/students/programs/inspiring-future-women-science

So far, we have talked about chemical reactions in terms of individual atoms and molecules. Although this works, most of the reactions occurring around us involve much larger amounts of chemicals. Even a tiny sample of a substance will contain millions, billions, or a hundred billion billions of atoms and molecules. How do we compare amounts of substances to each other in chemical terms when it is so difficult to count to a hundred billion billion? Actually, there are ways to do this, which we will explore in this chapter. In doing so, we will increase our understanding of stoichiometry, which is the study of the numerical relationships between the reactants and the products in a balanced chemical reaction.
