Question

please do BOTH graph 1 And graph 2 on excel please. data is attached

Evaporation, mm "ata Table 1: Measured temperatures for just ethanol and 1-propanol. You will be using the data from here to create a graph of Experimental AT versus molar mass Substance T. (°C) T2 (°C) Experimental AT (T.-T2) (°C) 146.07g/mol ethanol 9.2°C 11.6°C 20.8°C 60,09 g/mo 9.5°C 1-propanol 11.5°C 21.0°C Data Table 2: Measured temperatures for the other 4 liquids. You will be using the experimental AT values found here and comparing them to the extrapolated AT values calculated from the graph made from the data in data table 1. Substance T(°C) T2 (°C) Experimental AT Extrapolated AT (T-T2) (°C) (from graph you created) methanol 20.5°C 6.9°C 13.60 13.8°C 1-butanol 20.7°C 7.2°C 7.18° C acetone 21.1°C 18.3°C 9,670 butanone 20.4°C 7.3°C 13.1°C 7.4°C 13.5°C 2.8°C

Answer 1

Table 1
Substance	Experimental DT (C)	Molar Mass (g/mol)
ethanol	11.6	46.07
1-propanol	9.5	60.09

Graph 1 : Experimental Delta T vs Molar Mass 14 12 10 y=-0.149x + 18.50 R2 = 1 8 Experimental DeltaT(in C) 6 Graph 1 Linear (Graph 1) 4 2 0 1 1 1 1 7 0 10 20 30 40 50 60 70 Molar Mass (ing/mol)

Table 2 for Graph 2
Substance	Experimental DT (in C )	Molar Mass (g/mol)
methanol	13.6	32.04
ethanol	11.6	46.07
1-propanol	9.5	60.09
1-butanol	7.2	74.121

Graph 2: Experimental Delta T vs Molar Mass 16 14 12 10 Experimental Deltat (in C) 8 y = -0.151x + 18.53 R2 = 0.999 6 Graph 1 -Graph 2 Linear (Graph 2) 4 2 0 1 1 1 1 7 0 10 20 30 40 50 60 70 80 Molar Mass (ing/mol)
