Question 1

Calculate the average time for the tablet to dissolve in hot water. Record the average time in Table B.What is the average time it took for the tablet to dissolve in hot water?

Question 2

Answer:

$\boxed{ (t_d) = ((q - x) )/((w - x_w) + \theta) }$

Step-by-step explanation:

$let \: the \: quantity \: of \: the \: tablet \: be \to \: q \\ let \: the \: quantity \: of \: the \: water \: be \to \: w \\let \: the \: amount \: of \:tablet impurities \: be \to \: x_t \\ let \: the \: quantity \: of \: pure \: tablet \: be \to \: (q - x) \\ let \: the \: amount \: of \: heat \: (temp)\: be \to \: \theta\\let \: the \: amount \: of \:water \: impurities \: be \to \: x_w \\ let \: the \: quantity \: of \: pure \: water \: be \to \: (w - x_w) \\ hence \: the \: average \: time \: for \: dissolution : (t_d) \to \\ \boxed{ (t_d) = ((q - x) )/((w - x_w) + \theta) }$
