Answer:
The answer is 0, 506 mol
Explanation:
We calculate the weight of 1 mol of NaCl:
Weight 1 mol NaCl = Weight Na + Weight Cl= 23 g + 35, 5 g = 58, 5 g
58, 5 g----1 mol NaCl
29, 6 g----x= (29,6g x 1 mol NaCl)/ 58,5 g = 0,505982906 mol NaCl
<span>1 mole glucose gives 2 moles of ethanol
moles of glucose in 2.4 kg = 2400 / 180.18 = 13.320 moles
so moles of ethanol produced = 2* 13.32 = 26.64 moles
weight of ethanol 26.64 * 46.07
=1227.30 gm or 1.23 Kg</span>

To find the atomic mass, multiply the individual atomic masses with their relative abundances and add them up.
10.012*0.1991 + 11.009*0.8009 = 10.810 amu (5 s.f.)
