Answer:
Density in decimal can be written as 0.0001429 gram per liter
Step-by-step explanation:
We have given density of oxygen is
We have to convert this density in decimal form
We know that
can be written as![10^{-6}=\frac{1}{10000}=0.0001](https://tex.z-dn.net/?f=10%5E%7B-6%7D%3D%5Cfrac%7B1%7D%7B10000%7D%3D0.0001)
So![1.429\times 10^{-4}=1.55\times 0.0001=0.0001429 gram per liter](https://tex.z-dn.net/?f=1.429%5Ctimes%2010%5E%7B-4%7D%3D1.55%5Ctimes%200.0001%3D0.0001429%20gram%20per%20liter)
So density in decimal can be written as 0.0001429 gram per liter
