HI There!
Which of the following is NOT the same as 13.6 milliliters?- 0.0136 dkL
- 0.0136 L
- 0.136 dL
Answer:<span>0.0136 dkL</span>
Answer:
Magnesium has 2 valence electrons.
Explanation:
The atomic number of magnesium is 12. This means that it has 12 protons and 12 electrons. The first electron shell can hold 2 electrons, the second can hold 8, so the third will have 2 electrons. The outermost shell of the atom has two electrons. Therefore, magnesium has 2 valence electrons.
When molality = no.of moles of solute/weight Kg of solvent
and when we have the no. of moles of solute = 8.1 moles
and the weight Kg of the solvent =4847 g /1000 = 4.847 Kg
so by substitution :
Molarity = 8.1m / 4.847Kg = 1.67 M
