B. density is the right answer
Cirrus: feathered clouds
Cumulus: fluffy white clouds, dense vertical clouds
Stratus: smooth gray clouds that cover the whole sky
Answer and Explanation:
To calculate this, simply use an equality of proportions:
50 particles : 1 billion particles = <em>x</em> tons : 1.49 million tons
The value of <em>x</em> can be solved for by multiplying the ratio on the left by the value 1.49 million / 1 billion:
So, <em>x</em> = (50)(0.00149) tons = 0.0745 tons
Then, do the same thing for the larger concentration:
<em>x</em> = (200)(0.00149) tons = 0.298 tons

We are to find the mass of the hydrogen atoms in 1 mole of water.
We know that the formula of water is: 
We can see, from the above mentioned formula, that water has 2 hydrpgen atoms.
From the periodic table, we get to know that Hydrogen has an atomic mass of 1.00794 grams.
As there are 2 atoms of hydrogen in water so 
grams is the answer
