Answer: 631.8 g
Explanation:

It can be seen from the balanced chemical equation, 2 moles of ethane reacts with 7 moles of Oxygen gas to produce 4 moles of carbon dioxide and 6 moles of water.
Ethane is the limiting reagent as it limits the formation of product.
Thus, if 2 moles of ethane produce 6 moles of water.
11.7 moles moles of ethane produce=
of water.
Mass of water= no of moles
Molar mass
Mass of water= 35.1
18g/mol= 631.8 g
Answer:The key to remember is that carbon combustion requires oxygen. As soon as there is no oxygen left, carbon combustion stops. In nuclear fusion, the nuclei of atoms are fused together to make new, bigger nuclei.
Explanation:
Nitrogen is ...19.7
flourine is 80.3...
hope this helps!
Density is Mass per Volume
so
0,8765 g/ml = Mass of Benzene / 250 ml
Mass of Benzene = 219,125 gram
so 250 ml of benzene is equal to 219,125 gram
