PASSAGE BASED QUESTION Please read the passage given below and answer the questions: Q5. The process of separation of coloured components from a mixture is known as Chromatography. Kroma in Greek means colour. This technique was first used for the separation of those solutes that dissolve in the same solvent. The ink that we use has water as the solvent and the dye that is soluble in it. As the water rises on the filter paper, it takes along with it the dye particles. The different colours get separated in different bands of colours at different heights. (a) What is the solute and solvent in the blue black ink? (b) What type of coloured mixtures can be separated by Chromatography? (c) What do you observe as the water rises up on the filter paper? (d) Give any one application of Chromatography. |

How many molecules of benzene arethere in 1Lof C6H6 [d=0.88g/cm3]??? |
|
Answer» tion:Given -1 L C6H6, density(d) = 0.88 g/cm³To FIND -How many molecules of BENZENE are there in 1 L of C6H6Solution -d = m/v0.88 = m/1 × 1000M = 0.88 × 1000m = 880Now, As we know that -MOLE = mass/GMMn_{C6H6} = 880/78n_{C6H6} = 11.282Then, Number of molecules = n × 6.022 × 10²³= 11.282 × 6.022 × 10²³= 67.94 × 10²³Hence, The number of molecules present in 1 L of C6H6 is 67.94 × 10²³. |
