Suppose it takes 35 min for 2.4 g of sugar to completely react with another reagent we added to the flask. What would the reaction rate be?
Calculate to the correct number of significant figures.
rate = delta grams/delta time = 2.4/35 = ?
0.07
Well, if the reaction takes 35 min to completely react 2.4 g of sugar, we can calculate the reaction rate by dividing the amount of sugar by the time it takes. So, the reaction rate would be 2.4 g sugar / 35 min = 0.0686 g/min.
Now, since the number 35 has two significant figures and the number 2.4 has two significant figures as well, we will round our answer to two significant figures. Therefore, the reaction rate would be approximately 0.069 g/min.
But hey, don't worry too much about the significant figures, it's just sugar reacting in a flask, not a high-stakes comedy show!
To calculate the reaction rate, we need to determine the amount of reactant consumed per unit of time. In this case, the reactant is 2.4 g of sugar, and the time is 35 min.
The reaction rate can be calculated using the formula:
Reaction rate = Amount of reactant consumed / Time
Plugging in the values, we have:
Reaction rate = 2.4 g / 35 min
To determine the reaction rate to the correct number of significant figures, we need to consider the given values. The given value of 2.4 g contains two significant figures, and the given value of 35 min contains two significant figures as well.
Therefore, we can express the reaction rate to two significant figures:
Reaction rate = 0.069 g/min (rounded to two significant figures)
To calculate the reaction rate, we need to determine the amount of reactant consumed over time. In this case, we know that 2.4 g of sugar reacted in 35 minutes.
To find the reaction rate, we divide the amount of reactant consumed by the time taken:
Reaction rate = Amount of reactant consumed / Time
In this case, the amount of reactant consumed is 2.4 g of sugar, and the time taken is 35 minutes. Therefore, the reaction rate can be calculated as:
Reaction rate = 2.4 g / 35 min
To calculate it to the correct number of significant figures, we need to determine the least precise measured value, which is 2.4 g since it has three significant figures. Therefore, we will round our answer to three significant figures as well.
Using a calculator, the reaction rate can be evaluated as:
Reaction rate = 2.4 g / 35 min = 0.06857 g/min ≈ 0.0686 g/min
Therefore, the reaction rate would be approximately 0.0686 g/min, rounded to three significant figures.
