Question

Using the following data table and graph, calculate the average k from the data. Amount CO2 (mL) Amount of White Solid (g) y x 10 0.15 20 0.30 30 0.46 40 0.62 50 0.77

Answer 1

The k is the proportionality constant of the reaction. Graphically, this is the slope of the graph. Since the graph is linear, then there is only 1 value of k. To calculate this, choose two random points in the line. Suppose we use (0.15,10) and (0.30,20), calculate for the slope.

Slope = k = (10 - 20)/(0.15 - 0.30) = 66.67 mL CO₂/g CaCO₃

Answer 2

The correct answer its 60

i dont know why is the other answer verified if its wrong,

hope it was helpful uwu

can i get brainlyest please?
