Thanks so much, this melt my heart

Thanks for the important Question ⁉️ The problem we are given here was for 2 individual, the first row is your and the second row Folin Wu method.. First step: we need to use the t-test formula which calculate the t-statistics : Next: after that we use it to compare the critical t-value. Note n1 and n2 are simply No# of your Trials and the Folin Wu methods , yours is 7 and Folin Wu method is 6... Note: without knowing your Variance you can't use the t-test formula, you need to calculate your Variance and Folin Wu independently then subtitute into the equation... Also the two variances will be divided by n1 and n2 before you can add them together.. Feel free to go through the video one more time.. thanks

So what's the degree of Freedom.......why are you subtracting 1?

🤗🤗🤗🤗 thanks so much

Thank you to you atlist now I can come this side if you are busy to teach me

Kindly watch the beginning of the video again properly

Why are we not using the density

@@robertchambezi8590 because we are asked to calculate Mole fraction given the Density of solution = 1.202g/ml and concentration of solution= 20% for u to have your mass of KI u can multiply the density by the concentration

Thanks for the comments, but check it properly 🙏🙏🙏 feel free to Drop the correct solution

Thanks

Appreciate it!

Thanks!
