Question

Activity 1.5: Perform the following problems related to stoichiometry equation. 

A sample of saturated NaNO3 (aq) is 10.9 M at 25 degrees Celcius. How many grams of NaNO3 are in 230 mL of this solution at the same temperature?

What I Have Learned Activity 1.5: Perform the following problems related to stoichiometry equation. Choose only 2 problems to solve. 1. A certain laboratory procedure requires 0.025 M H2SO. How many milliliters of 1.10 M H;SO, should be diluted in water to prepare 0.500 L of 0.025 M H;SO.? 2. A sample of saturated NaNOs (aa) is 10.9 M at 25 degrees Celcius. How many grams of NaNO; are in 230 mL of this solution at the same temperature? 3. A beaker of 175 mL of 0.950 M NaCl is left uncovered for a period of time. If, by the end of the time period, the volume of solution in the beaker has decreased to 137 mL (the volume loss is due to water evaporation), what is the resulting concentration of the solution? 4. A student prepares a solution by dissolving 15.0 mL ethanol (C,H;OH) in water to make a 300.0 mL solution. Calculate the concentration (molarity) of ethanol in the solution. (density = 0.789 g/mL)
