WebAnswer : The molecular mass of a substance expressed in grams is called gram molecular mass or molar mass.A mole is a collection of 6.022 × 10 23 particles or a mole is defined … WebAnswer (1 of 8): As the number of molecules are ginormous even in grams of substances, a scientist named Avogadro introduced a concept known as the mole. It is used just like “dozen” or “pair” but to describe number of atoms in some amount of grams. Just like 1 dozen eggs are 12 eggs, 1 mole of e...

The number of gram molecules of oxygen in 6.02 - BYJU
WebIf we have 1 gram of hydrogen atoms, how many grams of oxygen would we have to have in order to have an equal number of oxygen atoms? Explain your answer. WebAnswer: 1 oxygen atom mass = 8 amu Now calculate no of atoms No of moles = (mass in grams)/molar mass Molecular mass = 16 g/mol No of moles = 1/16 No of moles = 0.0625 mol Then calculate no of molecules No of molecules = (no of moles)x Avogadro's number No of molecules = 0.0625 x 6.02x10^... WebThin and single MoS2 flakes are envisioned to contribute to the flexible nanoelectronics, particularly in sensing, optoelectronics and energy harvesting. Thus, it is important to study their stability and local surface reactivity. Their most straightforward surface reactions in this context pertain to thermally induced interactions with atmospheric oxygen. This review … generalization\u0027s as
