b.Calculate the number of moles of magnesium in the 0.0360 g sample
c.Calculate the number of moles of HCl(aq) needed to completely react with the sample ofmagnesium.
d.Given that the equilibrium vapor pressure of water is 21 torr at 23.00C, calculate the pressure that the H2gas produced in the reaction would have if it were dry.
e.Calculate the volume, in liters, measured at the conditions in the laboratory, that the H2(g) produced in the reaction would have if it were dry.
0.958atmf.The laboratory procedure specified that the concentration of the HCl solution be 2.0 M, but only 12.3 M HCl solution was available. Describe the steps for safely preparing 50.0 mL of 2.0 M HCl(aq) using 12.3 M HCl solution and materials selected from the list below. Show any necessary calculation(s).
M1V1= M2V2(12.3 M)V1= (2.0 M)(50.0 mL)V1= 8.1 mLPour some distilled water into a 50.00 mL volumetric flask so that it is about half full. Use thegraduated cylinder to measure 8.1 mL of the concentrated HCl then add that slowly to the volumetric flask and swirl to mix. Add more distilled water and fill to the line with the dropper. Cap and shake 13x’s.Answer the following questions in terms of principles of chemical bonding and intermolecular forces. In eachexplanation where a comparison is to be made, a complete answer must include a discussion of both substances. Consider the following molecules:a.At 1 atm and 298 K, pentane is a liquid whereas propane is a gas. Explain.
