Answer:
If we have one mole of water, then we know that it will have a mass of 2 grams (for 2 moles of H atoms) + 16 grams (for one mole O atom) = 18 grams.
Explanation:
It's depending on what size of the tree it is. For example, if the tree is large it will block most of the water that runs through. If the tree is small it shouldn't do as much besides block a little amount of water and it will probably go down stream.
This is based on my thinking
It is 14, plug it in or use inverse equations. Since they're vertical angles they are the same value. 41 = 2x+13, 28 = 2x (subtract 13), 14 = x (divide by 2).
Answer: 1.91cm3
Explanation:
10.49g of silver dissolves is 1cm3 of solution.
Therefore 20g of silver will dissolve in = 20/10.49 = 1.91cm3 of the solution.
Answer:
13.8%
Explanation:
take the 123g and divide it by the total mass which is 123g + 765g
123/888 = .138
multiply by 100 for a percentage = 13.8%
