Make a line graph of the data found above. On the same graph, show the average number of paper clips each electromagnet picked up for each voltage tested. Plot the voltage on the x-axis and the average
number of paper clips picked up on the y-axis. Scale the x-axis in intervals of 1.5 volts and scale the y-axis in intervals of 5 paper clips.

When 13.3 g koh is dissolved in 102.7 g of water in a coffee-cup calorimeter, the temperature rises from 21.4 °c to 31.53 °c. what is the enthalpy change per gram of koh (j/g) dissolved in the water? * take the density of water as 1.00 g/ml. * assume that the solution has a specific heat capacity of 4.18 j/g*k. enter to 1 decimal place. do not forget the appropriate sign /(+). canvas may auto-delete the (+) sign
