To get the molar mass of a compound, we add the masses of each element in the compound. Ions are charged atoms, and they can be either monatomic ions (single atoms) or polyatomic (multiple atoms combined to form a charged particle). We use the most common isotopes. Browse the list of All rights reserved. This site explains how to find molar mass. It is soluble in water and is mainly used as a coagulating agent (promoting particle collision by neutralizing charge) in the purification of drinking water and waste water treatment plants, and also in paper manufacturing. Molar mass of Al2(SO4)3 = 342.150876 g/mol. - Definition & Examples, Quiz & Worksheet - Alkanes Properties & Formula, Quiz & Worksheet - Double Displacement Reaction, Characteristics & Chemicals of Life Lesson Plans, CPA Subtest IV - Regulation (REG): Study Guide & Practice, CPA Subtest III - Financial Accounting & Reporting (FAR): Study Guide & Practice, ANCC Family Nurse Practitioner: Study Guide & Practice, Top 50 K-12 School Districts for Teachers in Georgia, Finding Good Online Homeschool Programs for the 2020-2021 School Year, Coronavirus Safety Tips for Students Headed Back to School, Parent's Guide for Supporting Stressed Students During the Coronavirus Pandemic, Ramon Barba: Biography, Contributions & Inventions, Effects of Development on Physiology & Pathophysiology, Implementing Risk Stratification in Clinical Practice, Evaluating the Impact of Clinical Nursing Specialist Practice on Systems of Care, Quiz & Worksheet - Situational Crime Prevention, Quiz & Worksheet - Paleolithic Period Weapons, Flashcards - Real Estate Marketing Basics, Flashcards - Promotional Marketing in Real Estate, High School Precalculus: Homework Help Resource, History of the Vietnam War for Teachers: Professional Development, Middle School Physical Science: Tutoring Solution, Interaction Among Organisms in the Ecosystem, Quiz & Worksheet - Craft a Strong College Application, Quiz & Worksheet - Weak Acids, Weak Bases, and Buffers, Quiz & Worksheet - The Cell Wall and Central Vacuole, Quiz & Worksheet - Poe's A Dream Within a Dream, Testimonials in Advertising: Definition & Examples. Multiplying the quantity of each element by its molar mass, and then adding it all together will give us the molar mass of aluminum sulfate. Password must contain at least one uppercase letter, a number and a special character. He has taught high school chemistry and physics for 14 years. Or if you need more Mole Concept practice, you can also practice Mole Concept practice problems. molar mass and molecular weight. The production of aluminum sulfate involves the reaction of aluminum hydroxide, sulfuric acid and water. Aluminum sulfate is an ionic compound, which is a combination of positive and negative ions. Since we have the formula for aluminum sulfate, we need to identify how many of each element make up the compound. In this case, our substance is aluminum sulfate, so we are going to determine the mass of one mole of it. The ­atomic masses are (from the periodic table): The molar mass of aluminum sulfate, Al2(SO4)3 (in g/mol) is? The formula weight is simply the weight in atomic mass units of all the atoms in a given formula. It is a hydrate, an aluminium salt, a metal sulfate and a potassium salt. The first step is the chemical reaction creating the compound, and the second step is making the solid into different size grains. … Aluminum forms a +3 ion, Al+3, and sulfate is the -2, polyatomic ion, (SO4)-2. 's' : ''}}. An ion is an atom or molecule that has a charge because it has too many or too few electrons. Aluminum sulfate is an ionic compound, which is a combination of positive and negative ions.
