a) What is the molarity of the solution that was prepared by
dissolving 3.25 g of sulfuric acid in water to a total volume of
500.0 mL?
b)What is the molarity of the hydrogen ion in part a if you
assume the sulfuric acid ionizes completely? Write a balanced
chemical equation.
what is the molarity? calculate the molarity of solution
containing 0.652 mol of glucose C6h12o6 in 255000 g of water
a solution contains 150.0 g of water (mw = 18.0 g/mol) and 50 g
of ethanol (MW = 44.0 g/mol ) wat are the mole fraction of water
and ethanol,and vapor pressure of the solution at 25 C (p water =
23.8 torr; p ethanol =58.7 torr)
Question 1: A solution of F– is prepared by dissolving 0.0712 ±
0.0005 g of NaF (molecular weight = 41.989 ± 0.001 g/mol) in 164.00
± 0.07 mL of water. Calculate the concentration of F– in solution
and its absolute uncertainty.
Question 20. A solution of HNO3 is standardized by reaction with
pure sodium carbonate.
A volume of 27.64 ± 0.05 mL of HNO3 solution was required for
complete reaction with 0.9875 ± 0.0009 g of Na2CO3, (FM 105.988 ±...
A solution is 3.24 M NH3 (MM 17.04 g/mol) in water
(MM 18.02 g/mol). The density of the resulting solution is 0.974
g/mL. What is the mole fraction, mass percent and molality of
NH3 in the solution?
A 360.0 −mL buffer solution is 0.160 M in HF and 0.160 M in
NaF.
What mass of NaOH could this
buffer neutralize before the pH rises above 4.00?
If the same volume of the buffer was 0.360 M in HF and 0.360 M
in NaF, what mass of NaOH could be handled before the
pH rises above 4.00?
