How many o atoms are in potassium carbonate
Web12 nov. 2015 · Nov 12, 2015 In 1 mole of potassium carbonate there are clearly 3 moles of oxygen atoms (i.e. 48.00 g), almost half the mass of 1 mol of the salt. Explanation: Moles of K2CO3 = 8.52⋅ g 131.21 ⋅ g ⋅ mol−1 = ?? mol. But there are 3 mol of oxygen in each mole of K2CO3. So moles of oxygen = 3 × 8.52⋅ g 131.21 ⋅ g ⋅ mol−1 =??mol. Answer link WebIn many cases, non-metals form more than one binary compound, so prefixes are used to distinguish them. Number Prefixes 1 Mono- 2 Di- 3 Tri- 4 Tetra- 5 Penta- 6 Hexa- 7 Hepta- 8 Octa- 9 Nona- 10 Deca-When only one atom if the first element is present, the prefix mono– is usually deleted from that part.
