Answer:

so the answer is A 5.199mol please. rate. me brainliest. if its. correct

Explanation:

N=nL

3.131 \times  {10}^{24} = n \times 6.022 \times  {10}^{23}  \\n =   \frac{3.131 \times  {10}^{24} }{6.022 \times  {10}^{23} }  \\ n = 5.199mol

3. The number of electrons and neutrons in an atom are 13 and 14, respectively. Find out the mass number, atomic number, valency
QveST [7]

Answer:

Explanation:

3. The number of electrons and neutrons in an atom are 13 and 14, respectively. Find out the mass number, atomic number, valency, and symbol of the element.

For a neutral atom. number of protons =number of electrons=13

so since atomic number is the number of protons =13

mass number = protons + neutons =14+13 = 27

atomic number 13 is Aluminum (AL-(see periodic table)

The electronic structure for 13 electrons is 1s2s2p63s23p1

so Al has 3 electrons which are VALIENT and can react and when it loses the 3 it will have  CHARGE OF +3

What is the mass of 0.714 moles of Mercury (I) Chloride (Hg2Cl2)?
ArbitrLikvidat [17]
Data:

m (<span>Sample Mass) = ? 
n (</span><span>Number of moles) = 0.714 mol
MM (Molar Mass) of </span>Mercury (I) Chloride (Hg_{2}  Cl_{2})
Hg = 2*200.59 = 401.18 amu
Cl = 2*35.453 = 70.906 amu
----------------------------------------
Molar Mass Hg_{2} Cl_{2} = 401.18 + 70.906 = 472.086 ≈ 472.09<span> amu or 472.09 g/mol
</span>
Formula:

n =  \frac{m}{MM}

Solving:


n = \frac{m}{MM}
0.714 =  \frac{m}{472.09}
m = 337.07226\:\to\:\boxed{\boxed{m\approx 337 g}} \end{array}}\qquad\quad\checkmark

Answer:
By approximation would be letter D) <span>337.2 g</span>
