Problem 62E

Problem 62E

(a) Calculate the molarity of a solution made by dissolving 12.5 grams of Na2CrO4 in enough water to form exactly 550 mL of solution.

(b) How many moles of KBr are present in 150 mL of a 0.275 M solution?

(c) How many milliliters of 6.1 M HCl solution are needed to obtain 0.100 mol of HCl?

Step-by-Step Solution:
Step 1 of 3

th th Chapter 7 from “Introductory Chemistry” by Zumdahl and Decoste, 7 /8 edition *Majority of the chemical reactions that take place in our bodies occur in aqueous solutions Ex: oxygen dissolving into blood stream Pg 137. PREDICTING IF A REACTION WILL HAPPEN Driving Force: “changes that make reactions go in the direction of the arrow,” the cause of the product Most common driving forces: 1. Forms a solid 2. Forms of water 3. Transfers electrons 4. Forms a gas -if two or more chemicals are joined together and any of these happened, there most likely is a chemical reaction REACTION: SOLID FORMS Precipitation: process by which a solid is formed Precipitate: the solid formed
