What is the fractions here? can you please insert a image.
Answer:
26.2ml
Explanation:
This is a delusion calculation. But before performing the delusion we need to know the concentration the polarity of the original solution. The original solution was prepared by taking .021 mg of ibuprofen and dissolving it in one mil leader. So to calculate the concentration, we need to take the moles of ibuprofen, which can be calculated by taking the milligrams divided by 1000 to get grams and then divided by the molar mass to get moles and dividing the moles of ibuprofen by the leaders of the solution. One mil leader can be calculated, Can be converted into a leader by dividing by 1000. We then get a polarity of 1.018 times 10 to the negative for Mueller Than to carry out the dilution. We have a 1.018 times 10 to the negative for Mueller solution and one mil leader of it. We want to prepare 375 times 10 to the negative six molar solution. And so we need to figure out what the new total volume will be Rearranging. This equation gives us a total volume of 27.15 million l but we already have one mil leader of solution. So we need to add to that The 27.15 -1 or the 26.15 ml. The answer then of the choices available would be 26.2 ml
Answer:
Fuel 1 changed phase because the energy drawn from it dropped its temperature below the transitional temperature that causes a phase change, fuel 2 still has its temperature well above the transitional temperature required to change phase.
Explanation:
For a substance to change phase, a transitional temperature has to be reached. This is because, the temperature of substances generally indicates the average kinetic energy of its molecules. An increase in energy input to the system will result in a change to a more mobile phase like from solid to a liquid state or from a liquid state to a gaseous state state, while taking energy from the system will cause a transition to a less mobile phase like gas to liquid or liquid to solid state.
