Explanation:
molarity=no. of moles of solute/solution in litres
6.17M=no. of moles of solute/9.4 L
6.17×9.4=no. of moles of solute
57.9 =no. of moles of potassium fluoride KF
no. of moles=given mass /molar mass
57.9=given mass/58
3358.2 g
What are you trying to find?
3)6 electrons and neon
<h3>Further explanation </h3>
In an atom there are levels of energy in the shell and sub shell
This energy level is expressed in the form of electron configurations.
The electron configuration Oxygen (atomic number = 8) :
<em>1s²2s²2p⁴</em>
Oxygen will try to achieve stability (according to the octet rule) by binding 2 electrons so that the 2p orbits are filled with 6 electrons, so that the configuration is stable like the noble gases Neon
<em>₁₀Ne = 1s² 2s² 2p⁶</em>
Nitrogen is often used for the storage of semen samples for artificial insemination of cattle. Nitrogen is used to maintain a dry inert atmosphere over chemicals during storage, reaction or processing. Used in brewing, soft drinks and wine-making industries to exclude air from the product and de-aerate water.
