WebSolution. The correct option is A 6.022×1025. From the formula unit of H2SO4, 4 moles of O− atoms are present in 1 mole of H2SO4. Therefore, 8 moles of O− atomes will be present in. = 8 4 moles of H2SO4. Again, the total number of electrons in one formula unit of (N H4)2SO4. = 2+16+8×4 =50. So, the total number of electrons in one mole of ...
WebThe mass number is equal to the atomic number plus the number of neutrons. So the mass number was right here, that's 12. So we can put in a 12. The atomic number was six, right here. So we put in a six. Plus the number of neutrons. Plus the number of neutrons. So the number of neutrons is just equal to 12 minus six, which is, of course, six. set windows 11 time serverWebJan 3, 2024 · Moles allow you to directly read weight from the periodic table (e.g., 1 mole of N₂ is 28 g or 1 mole of NaCl is 58.5 g). We can link the number of entities X in a specified sample – N(X), to the moles of X in the same sample – n(X), with the relation: n(X) = N(X)/NA.
