Question
The number of water molecules in 3, 6 g of water is 6.02 times 10^23 12.0 times 10^23 1.20 times 10^23 6.02 times 10^27 none of the above The process shown here is an example of, Mg(s) rightarrow Mg^2+(aq) + 2e^- oxidation reduction REDOX process None of these The mathematical expression of the ideal gas law is P_1V_1 = p_2v_2 P_1/T_1 =P_2/V_2 P_1/T_1 =P_2/V_2 PV = nRT P_T = P_1 + P_2 + P_3 Which of the following is NOT a postulate of the kinetic theory of gases? A gas is composed of very small particles. There is very little space occupied by gas molecules compare to the volume of container. Gas particles move rapidly. Gas particles do not attract or repel one another. Gas particles move faster when the temperature increases. The pressure exerted by the particles of vapor above a liquid is called the ______ vapour pressure barometric pressure standard pressure molor pressure atmospheric pressure How many grams of glucose, C_6H_12O_6 will be needed to prepare 250 mL of 0.1M sucrose solution in water? 180 grams 18.0 grams 1.80 grams 9.0 grams 4.5 grams A Bronsted base is; proton donor A proton acceptor A hydroxide donor A hydroxide acceptor An electron pair acceptorExplanation / Answer
Solution:
18. Given: 3.6 gram of water
we know avogadros number is 6.023 * 1023 unit per mole
We have 3.6 gram of water that is = 3.6/18 = 0.2 mole of water
S, by avogadros law, we can write in 0.2 mole of water,
= 6.023*1023 * 0.2 = 1.2 * 1023 water molecules
