Analyze Equation: Let's look at the equation m=0.15(8.6-s). The term 8.6-s is inside the parentheses, which means we subtract s from 8.6 before multiplying by 0.15.Subtract s from 8.6: Since s represents seconds after the start of the reaction, and it's being subtracted from 8.6, this suggests that 8.6 is the initial amount before any reaction time has passed.Calculate Initial Amount: If s were 0 (meaning at the start of the reaction), then m would be 0.15 times 8.6, which would be the initial amount of the reactant in moles.Interpretation of 8.6: Therefore, the best interpretation of the number 8.6 is that it represents the initial amount of reactant in moles.
