What is the mass in grams of 0.700 moles of water
1 answer:
Answer: 12.61 g of H2O
Explanation:
0.700 mol H2O x __18.016 g__ = 12.6112 g of H2O
1 mol H2O
Personally, I would round to 12.61 g of H2O, but round to however many significant figures asked for.
My chemistry teacher gave us this map (image attached) to teach us how to do conversions. Just follow the map. I think it's pretty straight forward. I hope this helps.

Answer:
E cell = +1.95 V
Explanation:
At Anode : Oxidation reaction takes place
At Cathode : Reduction reaction takes place
The reaction with lower value of reduction potential will undergo Oxidation
E = -1.18 V
This equation undergo oxidation reaction and become:
Anode(Oxidation-Half) :
E = +1.18 V
Cathode(Reduction-Half) :
E =+0.77 V
To balance the reaction multiply reduction-Half with 2.We get :
Note that E is intensive property , do not multiply E of oxidation-half with 2
Ecell = 0.77 -(-1.18)
E = +1.95 V
