Answer:
0.11mole
Explanation:
Let us assume that the condition is at standard temperature and pressure(STP);
Given parameters:
Volume of water = 2.45L
Unknown:
Number of moles found in this volume of water = ?
Solution;
At STP;
Number of moles =
Input the parameters and solve;
Number of moles of water = = 0.11mole
The number of moles of water found is 0.11mole
Answer:
C. 2.
Explanation:
The electronic configuration of the neutral atom is: 2,8,2.
So, it has 2 valence electrons that are able to create bonds.
<em>Thus, the right choice is: C. 2.</em>
