Question

Nitrogen has a melting point of -210.0°C and a boiling point of -195.8°C. A sample of nitrogen is heated from -215.0°C to -200.0°C. Which of the following best describes what happens to the nitrogen atoms during this transition?

Answer 1

Explanation:

When you're diluting a solution, you're essentially keeping the number of moles of solute constant while changing the total volume of the solution.

Now, let's assume that you don't know the equation for dilution calculations.

In this case, you can use the molarity and volume of the concentrated solution to determine how many moles of hydrochloric acid you start with.
