Kbr molar mass3/10/2023 Use the periodic table to find the molar masses of these two elements. Essentially, one formula unit of potassium bromide contains a potassium atom and a bromine atom. Potassium bromide is an ionic compound that is made up of potassium cations, #"K"^(+)#, and bromide anions, #"Br"^(-)#. Now, let's assume that you only have a periodic table to work with here. So, a compound's molar mass essentially tells you the mass of one mole of said compound. ![]() Now, enter the values appropriately and accordingly for the parameters as required by the example above where the Mass (m) is 22 kg and Number of moles (n) is 40 kg/mol.Īs you can see from the screenshot above, Nickzom Calculator – The Calculator Encyclopedia solves for the molar mass and presents the formula, workings and steps too.Your strategy here will be to use the molar mass of potassium bromide, #"KBr"#, as a conversion factor to help you find the mass of three moles of this compound. The screenshot below displays the page or activity to enter your values, to get the answer for the molar mass according to the respective parameters which are the Mass (m) and Number of moles (n). Now, Click on Molar Mass under Basic Chemistry After multiplying the masses and number of quantities we get 60.05 grams per mole. Since the atomic masses of carbon, oxygen and hydrogen are 12.01, 16.00 and 1.008, respectively. Once, you have obtained the calculator encyclopedia app, proceed to the Calculator Map, then click on Basic Chemistry under Chemistry We will multiply the atomic mass of carbon by 2, oxygen by 2 and hydrogen by 4 and then add the results to get the total molar mass in grams per mole. To get access to the professional version via web, you need to register and subscribe for NGN 1,500 per annum to have utter access to all functionalities. You can get this app via any of these means: If 1 mol of KBr weights 119 g, then 0.375 moles we need to prepare the solution weights x. To get the answer and workings of the molar mass using the Nickzom Calculator – The Calculator Encyclopedia. First, you need to obtain the app. Generally, we find the Molecular weight (Molar mass) of the solute KBr, K atomic weight + Br atomic weight KBr molecular weight 39 g/mol + 80 g/mol 119 g/mol The molecular weight means that 1 mol of KBr weights 119g. ![]() Nickzom Calculator – The Calculator Encyclopedia is capable of calculating the molar mass. Therefore, the number of moles is 0.55 mol. Therefore, the mass of a substance is 450 kg.Ĭalculating the Number of Moles of a Substance when the Molar Mass and the Mass is Givenįind the number of moles of a substance with a mass of 22 kg and molar mass of 40 Kg/mol. The formula for calculating the molar mass:įind the molar mass of a substance with a mass of 14 kg and number of moles of 28 mol.Ĭalculating the Mass of a Substance when the Molar Mass and the Number of Moles is Given.įind the mass of a substance with a molar mass of 30 Kg/mol and number of moles of 15 mol. To compute for the molar mass, two essential parameters are needed and these parameters are mass (m) and number of moles (n). The image above represents the molar mass of a substance.
