hello, i need help with these questions. i provided the measurements that I obtained during the experiment. I just need help with the calculations. Thank you!

Data Table B: Pressure Mole Relationship Trials Mass (9) NaHCO, 1 2.000 2 4.080 3 8.000 12g 5 16 g T6 Volume (mL) HCI 10mL 15mL 30 ML 50 65 75 Circumference balloon (cm) 31cm 10.2cm 65.3cm 59.5 4 67.5 71.9 20g Part B: Pressure and mole relationship 1. Sodium bicarbonate reacts with hydrochloric acid according to the following reaction: NaHCO, (s) + HCl (aq) CO2(g) + H2O (1)+ NaCl (aq). Calculate the moles of CO (g) that formed from your mass of NaHCO, (5) from trial #1, #2 and #3. (Molar mass of NaHCO; (5)=84.01 g/mol) 2. Calculate radius from circumference of your balloon in trials #1, #2, and #3 (circumference of a circle = 2.tr) Calculate volume (cm) of your balloon using the radii you got in #2 for trials #1, #2, and #3. (V of a sphere =(4/3) #r) Prepare a graph that displays the volume moles of CO (g) vs volume of balloon (include data from groups #4, #5, #6 in your graph). Based on this graph, what can you conclude about the relationship between moles of gas and volume? What are possible sources of error in this experiment and how could you better address it should ye repeat the experiment
