25mL of 0.1M NaCl contains _________ grams of NaCl.

Which solution has the lowest pH? 0.1M NaOH 0.1M H2SO4 0.1M HCN 0.1M H2CO3 0.1M NaCl
To prepare a solution that contains 1.20 moles of NaCl, how many grams of NaCl are needed? None 23.0 g NaCl 70.1 g NaCl 58.44 g
Why does the second drop of 0.1M HCl added to 0.1M NaCl change the PH less than the first drp of 0.1M HCl?
An aqueous solution of sodium chloride, NaCl, contains 2.18 grams of sodium chloride and 17.3 grams of water. The percentage by mass of sodium chloride in the solution is_______ %.
Calculate the number of grams of 5.0 % (m/m) NaCl solution that contains 6.30 g of NaCl. Calculate the volume in milliliters of 45 % (m/v) NaF solution that contains 2.0 g of NaF. Calculate the volume in milliliters of 8.5 % (v/v) ethanol solution that contains 30.4 mL of ethanol.
Calculate the number of grams of 4.4 % (m/m) NaCl solution that contains 6.20 g of NaCl. Calculate the volume in milliliters of 30 % (m/v) NaF solution that contains 4.3 g of NaF. Calculate the volume in milliliters of 7.0 % (v/v) ethanol solution that contains 10.2 mL of ethanol. Help please! I do not understand what to do with the percents.
The question is: 8) A solution contains 150.8 grams of NaCl in 678.3 grams of water. Calculate the vapor pressure of water (in torr) over the solution at 25.0 °C. (Note: The vapor pressure of pure water at 25.0 °C is 23.76 torr.) The correct answer is 20.90 but I get 22.236. I presumed I needed to use Raoult's law. Found the mole fraction for WATER, at .935864 and multiplied that by 23.76. But my doesn't match the answer sheet....
A solution contains 21.04 grams of NaCl in 0.225 kg water at 25°C. What is the vapor pressure of the solution? (The vapor pressure of pure water is 23.7 torrat 25 °C.)
Explain why equal volumes of 0.1M CH3COOH and 0.1M CH3CO2- function as a buffer solution, but equal volumes of 0.1M HCl and 0.1M NaCl or equal volumes of 0.1M HCl and 0.1M NaOH do not.
k. How would you prepare a solution of 250 ml SN buffer (0.1M NaCl, 50mM EDTA, 1mM Tris) if given NaCl solid (gram molecular weight = 58.44), a 5M stock EDTA, and a 100mm stock Tris?
