WebExplain why. a) As each mole consists of same number of atoms or molecules i.e. (6.022 ×10^23) , therefore one mole of H2, one mole of O2 and one mole of F2 have same number of molecules. b) Mass of 1 mole of substance is known as its molar mass. Thus , mass of 1 mole of H2 = 2× (1.0 g/mol) = 2.0 g/mol. WebAug 20, 2024 · A 0.150 M solution of formic acid at 25°C (pKa = 3.75) has a pH of 2.28 and is 3.5% ionized. Is there a change to the pH of the solution if enough solid sodium formate is added to make the final formate concentration 0.100 M (assume that the formic acid concentration does not change)?
