Asolution is created by dissolving 13.0 grams of ammonium chloride in enough water to make 295 ml of solution. how many moles of ammonium chloride are present in the resulting solution? =0.243 moleswhen thinking about the amount of solute present in a solution, chemists report the concentration or molarity of the solution. molarity is calculated as moles of solute per liter of solution. what is the molarity of the solution described above? =0.824 mto carry out a particular reaction, you determine that you need 0.0500 moles of ammonium chloride. what volume of the solution described above will you need to complete the reaction without any leftover nh4cl? ml of solution?

Electromagnets coils of wire paper clips picked up 10 3 15 6 20 9 25 12 ms. owens' class was studying magnets. ms. owens showed her students how to make an electromagnet using a nail, a d-cell battery, and plastic coated wire. the students wrapped the wire around the nail and then attached the ends to the battery. when they were finished, they tested their magnets by investigating how many paperclips their magnets could pick up. they also tested whether they could increase the strength of their electromagnets by using more coils of wire. they recorded the class average of their results in the data table seen here. ms. owens asked her students to graph their data in a line graph. how should the students label the x-axis on their line graph? a) size of battery b) number of paper clips c) number of coils of wire d) strength of electromagnet
