Answer:
FOR H_2
![1 \mu mol/L = 2\times 10^{-6} mol/L](https://tex.z-dn.net/?f=1%20%5Cmu%20mol%2FL%20%3D%202%5Ctimes%2010%5E%7B-6%7D%20mol%2FL)
Step-by-step explanation:
Given data:
concentration ![0.6 \mu mol/L](https://tex.z-dn.net/?f=0.6%20%5Cmu%20mol%2FL)
WE KNOW THAT
![ONE\ \mu = 10^{-6}](https://tex.z-dn.net/?f=ONE%5C%20%20%5Cmu%20%3D%2010%5E%7B-6%7D)
therefore
![1 \mu mol/L = 10^{-6} mol/L](https://tex.z-dn.net/?f=1%20%5Cmu%20mol%2FL%20%3D%2010%5E%7B-6%7D%20mol%2FL)
Now for conversion of mol to gram need the molar mass of element in which particular value convert to.
let us take ![H_2](https://tex.z-dn.net/?f=H_2)
we know that molar mass of
is 2 gram
therefore
![1 \mu mol/L = 2\times 10^{-6} mol/L](https://tex.z-dn.net/?f=1%20%5Cmu%20mol%2FL%20%3D%202%5Ctimes%2010%5E%7B-6%7D%20mol%2FL)
let take other example, for ![O_2](https://tex.z-dn.net/?f=O_2)
we know that molar mass of O_2 is 32 gram
therefore
![1 \mu mol/L = 32\times 10^{-6} mol/L](https://tex.z-dn.net/?f=1%20%5Cmu%20mol%2FL%20%3D%2032%5Ctimes%2010%5E%7B-6%7D%20mol%2FL)
Answer:
16, sqrt 256
Step-by-step explanation:
Geometric mean= √ ( 1/2 X 2/5 )
= 1/√5
The equation representing this situation would be 3 + 2x = c, where c is the total cost.
To find the cost to bring 12 dogs, you will replace the x with the number 12.
3 + 2 x 12 = 27
The cost would be $27.
