An aqueous solution is to be prepared that will be 5.25% by mass ammonium nitrate. What mass of NH4NO3 and what mass of water will be needed to prepare 1.21 kg of the solution? Mass = g NH4NO3 Mass g water A sample of an iron alloy contains 89.6 g Fe, 2.17 g C, and 1.58 g Cr. Calculate the percent by mass of each component present in the alloy sample. % Fe %C % Cr
What mass of potassium nitrate (M = 101.1 g//mol) is required to prepare 300 mL of 0.1 M solution? b) What will be the concentration of potassium ions if extra 10 g of potassium sulfate (M = 174.3 g/mol) are added? Assume that the volume of the salt is negligible.
An aqueous solution is to be prepared that will be 7.43% by mass ammonium nitrate. What mass of NH4NO3 and what mass of water will be needed to prepare 1.28 kg of the solution?
Instant cold packs, often used to ice athletic injuries on the field, contain ammonium nitrate and water separated by a thin plastic divider. When the divider is broken, the ammonium nitrate dissolves according to the following endothermic reaction: NH4NO3(s) → NH(aq) + NO3 (aq) In order to measure the enthalpy change for this reaction, 1.25 g of NH4NO3 is dissolved in enough water to make 25.0 mL of solution. The initial temperature is 25.8 °C and the final temperature (after...
The change in enthalpy for dissolving ammonium nitrate in water is 26 kJ/mol. Determine the amount of ammonium nitrate (in grams) that was dissolved in water to make 50.0 mL of solution if the temperature of a coffee cup calorimeter changes from 25.3°C to 21.5°C. Assume the density of the solution is 1.0 g/mL and the heat capacity of the solution is 4.2 J/g°C.
Suppose 0.0948 g of ammonium nitrate is dissolved in 50 mL of a 39.0 m M aqueous solution of sodium chromate. Calculate the final molarity of nitrate anion in the solution. You can assume the volume of the solution doesn't change when the ammonium nitrate is dissolved in it Round your answer to 2 significant digits.
