368 g NO2 gas is given. Find the answers of each one given below, a. GMM of NO2 b. Number of moles of molecules of 368 g NO2 c. Number of molecules d. Number of atoms e. Volume in STP |
|
Answer» a. GMM of NO2 = 14 + 2 × 16 = 46 g b. Number of mole = \(\frac{368}{46}\) = 8 c. Number of molecules = Number of moles × NA = 8 × 6.022 × 1023 d. Number of atoms = Number of atoms in one molecule × Number of molecules = 3 × 8 × 6.022 × 1023 = 24 × 6.022 × 1023 e. Volume in STP = Number of moles × 22.4 L = 8 × 22.4 L = 179.2 L |
