Question

2. From the above graph, determine the pressure in torr if the volume is 84.2 mL. Show your work below: .68 3. Give the SI unit for pressure 4. Give the SI unit for volume 125

Answer 1

There is error in the plot of the graph . Below attached is the image of graph obtained from the given data using excel.

From there we can find the equation of given line that comes

P = 25.434(1/V)

You can also find the slope of line by using formula m= (p2-p1)/(v2-v1) = (0.282-0.254)/(0.0111-0.01) =25.45 {or by using any two points )

subsituting v= 84.2 ml

we get P= 0.302067atm (1 atm = 760 torr ) =229.5705 torr

SI unit of pressure is pascal ( 1 atm = 101325Pa or N/m2 )

SI unit of volume is m³ ( 1m³=1000L )
