Web5 jun. 2024 · Based on our assumption, [H3O +]eq = [HA]initial, so we can carry out the following calculation: pH = − log([H3O +]eq) = − log([HA]initial) Example 1 What is the pH of a 0.175 M aqueous solution of HBr? Solution HBr is a strong acid ( Ka > 1 ), so [H3O +]eq = [HBr]initial. Thus, pH = -log (0.175) = 0.757 Exercise 1 Web1 feb. 2024 · In order to find how many electrons an atom has, you simply look at the atomic number. The number of electrons = the atomic number.

Web3 jul. 2024 · Atoms and Ions. Atoms are the smallest unit of matter that can't be broken down chemically. Molecules are groups of two or more atoms that are chemically bonded. Ions are atoms or molecules that have gained or lost one or more of their valence electrons and therefore have a net positive or negative charge. An atom can be an ion, but not all ... Web17 sep. 2014 · We need to convert this into mol.dm−3 . To do this we add up the Ar values to get the relative formula mass. For NaCl this will be 23 +35.5 = 58.5. So 1 mole of NaCl weighs 58.5g. So now we need to convert grams into moles by dividing mass in grams by the mass of 1 mole. So the number of moles of NaCl = 58.5/58.5 = 1 mole resources for real estate agents https://milton-around-the-world.com
