Answer:
Number of moles = 0.94 mol
Explanation:
Given data:
Number of moles of sodium chloride = ?
Volume of sodium chloride = 1.25 L
Concentration of solution = 0.750 mol/L
Solution:
Formula:
Concentration = number of moles/ volume in L
By putting values.
0.750 mol/L = number of mole / 1.25 L
Number of moles = 0.750 mol/L×1.25 L
Number of moles = 0.94 mol
Explanation: Once swallowed, a drink enters the stomach and small intestine, where small blood vessels carry it to the bloodstream. Approximately 20% of alcohol is absorbed through the stomach and most of the remaining 80% is absorbed through the small intestine.

We have to calculate amount of zinc formed in the given reaction.
The amount of zinc formed is 16.47 g.
The balanced chemical reaction between copper and zinc nitrate is as follows:
2Cu (s) + Zn(NO₃)₂ (aq) → Zn (s) + 2CuNO₃ (aq)
From the reaction it is clear that one mole Zn is produced from two moles of Cu.
Atomic mass of copper is = 63.5 g and atomic mass of zinc is = 65.38 g.
As per reaction, 2 X 63.5 g= 127 g of copper produces 65.389 g of zinc. Therefore 32 g copper will produce g = 16.47 g of zinc.
