Homework Statement (Q.) 3 g of activated charcoal was added to 50 mL of acetic acid solution (0.06N) in a flask. After an hour it was filtered and the strength of the filtrate was found to be 0.042 N. The amount of acetic acid adsorbed (per gram of charcoal) is :Homework Equations...
The chemical formula of glucose is: {eq}\rm C_6H_{12}O_6 {/eq}. There are 12 moles of H per mole of glucose. In order to determine the mass in grams... Learn more about this topic: Molar Mass | Definition, Formula & Examples from Chapter 28/ Lesson 24 749K What is molar ma...
016 AMU. A mol of hydrogen gas has a mass of 2.016 grams. In that 2.016 gram mass is Avogadro’s number of H2 molecules because that is the way hydrogen comes. A mol of water is 18.016 grams because each water molecule has two hydrogen atoms and one oxygen atom. A mol of water ...
water has the formula H2O indicating each molecule contains two atoms of hydrogen and one atom of oxygen. The number of moles for each substance is written before the formula with values of one mole not written. Two moles of water is written as 2 H2O and 1.8 moles of water is written as...
Is it due to oxygen or nitrogen? How can we tell how atoms react with each other by looking at the periodic table and how can we tell if an electron has been removed or added from an atom? What mass of copper(II) nitrate, Cu(NO_3)_2, must be decomposed to produce 1500 g of ...
How many moles of NH3 are there in a 12.50gram sample? Number of Moles of Sample: When the total molar mass of a substance from a table of standard values is represented as M, then we'll divide the number of grams by this value for the total number of moles of the sample. Answ...
Calculate the number of millimoles (mmol) of citric acid found in 1.00 g of citric acid. (1 mmol = {eq}1 \times 10^{-3} {/eq} mol) Molar Mass: The molar mass is a quantity of substances that defines the mass per mole. This is the key quantit...
(sucrose) by finding the atomic mass of each atom in the solution. This can be done using theperiodic table. The chemical formula for sucrose is C12H22O11:12 carbon, 22 hydrogen, and 11 oxygen. You will need to multiply the atomic mass of each atom by the number of atoms of that ...
