Answer:
"23.896%" is the right answer.
Explanation:
The given values are:
Mass of NaCl,
= 51.56 g
Mass of H₂O,
= 165.6 g
As we know,
⇒ Mass of solution = ![Mass \ of \ (NaCl+H_2O)](https://tex.z-dn.net/?f=Mass%20%5C%20of%20%5C%20%28NaCl%2BH_2O%29)
= ![51.56+164.2](https://tex.z-dn.net/?f=51.56%2B164.2)
= ![215.76 \ g](https://tex.z-dn.net/?f=215.76%20%5C%20g)
hence,
⇒ ![Mass \ percent =\frac{Mass \ of \ NaCl}{Mass \ of \ solution}\times 100](https://tex.z-dn.net/?f=Mass%20%5C%20percent%20%3D%5Cfrac%7BMass%20%5C%20of%20%5C%20NaCl%7D%7BMass%20%5C%20of%20%5C%20solution%7D%5Ctimes%20100)
![=\frac{51.56}{215.76}\times 100](https://tex.z-dn.net/?f=%3D%5Cfrac%7B51.56%7D%7B215.76%7D%5Ctimes%20100)
![=23.896 \ percent](https://tex.z-dn.net/?f=%3D23.896%20%5C%20percent)
At diverging plate boundaries, earthquakes occurs as the plates pull away from each other. Volcanoes form between the plates, as magma rises upward from the underlying mantle. Second, two plates may come together, at a converging plate boundary. Two situations are possible at converging plate boundaries.
Answer:
Number of neutrons is equal to 148.
Answer:
Cooffee
Explanation:
<em>the answer is coffee because coffee might be bitter</em>
N = ?
T = 449 K
V = 58.35 L
P =2.97
R = 0.082
Use the clapeyron equation:
P x V = n x R x T
2.97 x 58.35 = n x 0.082 x 449
173.2995 = n x 36.818
n = 173.2995 / 36.818
n = 4.70 moles
hope this helps!
