A study was made of the effect of temperature on the volume of 2.00 g of helium (He) gas, with the pressure held constant at 3 atm. The data for this experiment were: T. (°C) V. (L) -50.00 3.050 -10.00 3.196 0.00 4.233 25.00 4.575 50.00 4.416 100.00 5.200 Graph the volume vs the temperature. Round to three places after the decimal point and include the leading zero before the decimal point in your answers. R2. slope - y-intercept

Answer question number one, please.

Answer question 11, Mass % HCI in sample. Then, show your setup for the calculation of the molarity of the HCI for Trial. For the last section, show your setup for the calculation of the percent HCI in the solution. (Use the chart for reference)

In synthesizing aspirin, a student used 5.324 g of salicylic acid and excess acetic anhydride.  After recrystallization, the product weighed 6.362 g.  Calculate the percent yield of aspirin.

Analytical chemistry

Nicotine is a naturally produced alkaloid and is widely used recreationally as a stimulant that produces pleasing effects in brain making it addictive. It is composed 74.017% C, 8.714% H and 17.269% N. In 1.00-g sample of nicotine contains 6.163X10^-3 moles. Determine its molecular formula? Please show the complete solution and write clearly. Thank you.
