Answer:
2.20752 x [tex]10^{24}[/tex]
Step-by-step explanation:
The first thing you have to do is to look for the number of seconds in one year. You have to multiply 365 days by 86,400 seconds.
- 365 days refer to the total number of days per year
- 86,400 seconds refer to the number of seconds per day
Let's solve.
- 365 x 86,400 = 31,536,000 or 3.1536 x [tex]10^{7}[/tex]
Therefore, one year has 3.1536 x [tex]10^{7}[/tex] seconds.
Next, you have to know the number of seconds in 10 billion years.
- (3.1536 x [tex]10^{7}[/tex]) x  (1.0 x [tex]10^{10}[/tex]) = 3.1536 x [tex]10^{17}[/tex]
The last step is to multiply the number of seconds in 10 billion years to 7 million tons of mass per second.
- (3.1536 x [tex]10^{17}[/tex]) x 7,000,000 = 2.20752 x [tex]10^{24}[/tex]
