The c of the water or specific heat of water is 4 if the temperature is 25 degrees c and cubic meter in air. Contain 22 grams
Answer:
Explanation:
Total weight of 5 rings
= 18 x 5
= 90 g
silver = 10% of 90 g
= 9 g
gold = 81 g
Let silver added = x gm
Total weight = 90 +x
75% of (90+x) is gold
= 3/4 x (90+x)g is gold
So 3/4 x (90+x) = 81
(90+x) = 81 x 4 / 3
= 108
x = 18 g
silver to be added = 18g .

Explanation:
This is a pretty straightforward example of how to sue Avogadro's number to figure out the number of molecules present in a given sample.
In your case, the sample is said to contain
2.50
moles of water. Now, a mole is simply a very, very large collection of molecules. In order to have
1
mole of a molecular compound you need your sample to contain
6.022

23
molecules of that compound.

<span>If you placed the letter g under a microscope, the image in the field would look completely inverted. So, instead of seeing a regular letter g, it would be inverted both from up to down and from left to right, so when you look at the letter under a microscope, it would no longer look like the letter g, but rather like the number 6. This would happen because of the convex lens which tends to invert, or flip images.</span>
