Question
A scientist uses 3 kilograms of sodium every 5 minutes during an experiment.If the experiment lasted 1 hour, how many total grams of sodium did they use?A)36B)0.36C)36,000D)360
Solution
First, we need to convert the time of the experiment from hours to minutes because the rate at which the scientist uses sodium is given in kilograms per 5 minutes.
1 hour = 60 minutes
Next, we need to find out how many 5-minute intervals are in 60 minutes.
60 minutes ÷ 5 minutes = 12 intervals
The scientist uses 3 kilograms of sodium every 5 minutes, so in 12 intervals, they would use:
3 kilograms/interval x 12 intervals = 36 kilograms
However, the question asks for the answer in grams, not kilograms. We know that 1 kilogram = 1,000 grams, so:
36 kilograms x 1,000 grams/kilogram = 36,000 grams
So, the scientist used 36,000 grams of sodium in total during the 1-hour experiment. The correct answer is C) 36,000.
