How many molecules are present in 7 × 10-3 m3 of NH3 at STP? |
|
Answer» Molar volume = 22.4 dm3 = 2.24 × 10-2 m3 2.24 × 10-2 m3 of NH3 at STP contains 6.023 × 10 23 NH3 molecules. :. 7 × 10-3 m3 of NH3 will contain = \(\frac{6.023\times10^{23}}{2.24\times10^{-2}}\) x 7 x 10-3 18.82 × 1022 NH3 molecule |
