Calculate the molarity of each of the following solutions. Part A - 0.14mol of LiNO3 in 6.0L of solution. Express your answer using two significant figures. Part B - 1.57mol of LiCl in 34.2L of solution. Express your answer using three significant figures. Part C - 0.0441mol of glucose in 88.2mL of solution. Express your answer using three significant figures.
an unknown compound has the following chemical formula crohx where x stands for a whole number. measurements also show
why is it important to standardize NaOH solution instead of taking an accurate and diluting it in a volumetric
calculate the empirical formula of hydrated ferrous ammonium sulfate feanh4bso4ch2od from the following data.a. 0.7840
A sample of hydrogen gas was collected over water at 36°C and 855 mm Hg. The volume of the container was 6.50 L. Calculate the mass of H2(g) collected. (Vapor pressure of water = 44.6 torr at 36°C)
Calculate the grams of O2 gas that will have the same volume as 300.0 g of N2 gas at 10 degrees C and 5 atm
What is the pH at the half-stoichiometric point (that is, what is the pH when you have added 50% of the total volume of base required to react with all of the acid originally present?)
Write a net ionic equation to explain why the pH didn't go up to about 10, as it would have if that amount of NaOH were added to distilled water or to 20ml 0.00040 M HCL, which also would have a pH of 3.40
Calculate the percent ionization of 7.5×10?3 M butanoic acid in a solution containing 7.0×10?2 M sodium butanoate.
What characteristic H NMR absorptions would be expected in the aliphatic region for 9-hydroxyfluorene
Give the symbol of the element in the fifth period of the periodic table with five valence electrons, Give the symbol of the element in the fourth period of the periodic table with four 4p electrons
Determine the final volume (mL) for each of the following: a) diluting 2.50 mL of an 8.00 M KOH solution to give a 2.00 M KOH solution. b) diluting 50.0 mL of a 12.0 M NH4Cl solution to give a 2.00 M NH4Cl solution. c)diluting 75.0 mL of a 6.00 M ..
The element is so highly unstable that no observations of its properties have been possible. Based on its position in the periodic table, propose two different reasonable valence electron configurations for this element.
