Question

There are 2.60 x 1015 short tons of oxygen in the atmosphere ( 1 short ton = 2000 lb). How many metric tons of oxygen are oresent (1 metric ton =1000 kg) ?

Answer 1

Answer:
`2.36* 10^(15)` metric tons of oxygen is present.

Step-by-step explanation:

We are given:

Mass of oxygen in atmosphere =
`2.60* 10^(15)\text{ short tons}`

To convert it into metric tons, we use the conversion factors:

`1\text{ short ton}=2000lb`

And,

`1\text{ metric ton}=2204.62lb`

Converting short tons into pounds, we get:

`\Rightarrow 2.60* 10^(15)\text{ short tons}* (\frac{2000lb}{\text{1 short ton}})=5.2* 10^(18)lb`

Now, converting the given mass in pounds to metric tons, we get:

`\Rightarrow 5.2* 10^(18)lb* (\frac{\text{1 metric ton}}{2204.62lb})=2.36* 10^(15)\text{metric ton}`

Hence,
`2.36* 10^(15)` metric tons of oxygen is present.
