Answer:
~.1058 Moles
Explanation:
The formula for this question is the following.
1 mole of a compound/molar mass of the compound.
First we need to find the molar mass of H2O, which is the atomic mass on the periodic table. Hydrogen is 1.01, Oxygen is 16.00. Add those together to get the molar mass of the compound and you'll get an equation that looks like this.
1 mole of H2O/ 17.01 g/mol H2O
We now know that in 1 mole of H20 there is 17.01 g.
Take 1.8g and divide it by 17.01, you get your answer.
Answer:
A) 
Explanation:
m = Mass of water = 38.9
M = Molar mass of water = 18 g/mol
= Avogadro's number = 
The reaction of electrolysis would be
Number of moles of 
From the reaction it can be seen that 2 moles of gives 1 mole of 
So, number of moles of produced is
Number of molecules
So, of oxygen is produced.
