Answer: [tex]2.36\times 10^{15}[/tex] metric tons of oxygen is present.
Explanation:
We are given:
Mass of oxygen in atmosphere = [tex]2.60\times 10^{15}\text{ short tons}[/tex]
To convert it into metric tons, we use the conversion factors:
[tex]1\text{ short ton}=2000lb[/tex]
And,
[tex]1\text{ metric ton}=2204.62lb[/tex]
Converting short tons into pounds, we get:
[tex]\Rightarrow 2.60\times 10^{15}\text{ short tons}\times (\frac{2000lb}{\text{1 short ton}})=5.2\times 10^{18}lb[/tex]
Now, converting the given mass in pounds to metric tons, we get:
[tex]\Rightarrow 5.2\times 10^{18}lb\times (\frac{\text{1 metric ton}}{2204.62lb})=2.36\times 10^{15}\text{metric ton}[/tex]
Hence, [tex]2.36\times 10^{15}[/tex] metric tons of oxygen is present.
