Answer:
The reaction take 2.05 hours.
Step-by-step explanation:
Given : A chemical reaction took 7380 seconds.
To find : How many hours did the reaction take?
Solution : We have to convert seconds into hours.
1 hour = 60 minutes
1 minute = 60 seconds
[tex]1 \text{seconds}= 60\times 60 \text{hours}[/tex]
[tex]1 \text{seconds}= \frac{1}{60\times 60} \text{hours}[/tex]
[tex]7380 \text{seconds}= \frac{7380}{60\times 60} \text{hours}[/tex]
[tex]7380 \text{seconds}= 2.05 \text{hours}[/tex]
Nearest to hundredth the reaction take 2.05 hours.
