Answer:
1
Explanation:
I would say 1 because that configuration has 7 valence electrons. The goal of the atom is to gain a full octet so it just needs to gain 1 more electron to get the full octet. To get the one electron to fill the valence shell it would only need to have 1 covalent bond.
I hope this helps. Let me know if anything is unclear.
Hello!
First you have to find the molar mass of the molecules
C = 12
O = 16
2Cl = 71
6H2O = 108
Add them up to find the total molar mass
12 + 16 + 71 + 108 = 207g/mol
Divide the amount of water by the total molar mass
108 / 207 = 0.5217
Convert this to a decimal
0.5217 = 52.17%
The answer is 52.17%
Hope this helps!
The solution 550 ml total and first we will find the amount of alcohol. 3% = 0.03 550 ml x .03 = 16.5 ml alcohol
Then to find the amount of water used, we just have to subtract the amount of alcohol from the total volume
550 ml total - 16.5 ml alcohol = 533.5 ml water
