Answer to Question #308420 in General Chemistry for Krix

Question

Convert the following number of moles into their corresponding number of particles.

10. 0.0455 moles of hydrochloric acid

11. 1.2 moles of glucose (C6H12O6)

12. 0.32 moles of sodium bicarbonate

Answer 1

10.

H⁺ $\to6.022×10^{23}×0.0455$ H⁺ ions

$=2.74×10^{22}$

Cl^- $\to2.74×10^{22}$ Cl^- ions

11.

C $\to1.2×6.022×10^{23}×6$

$=4.34×10^{24}$ Particles

H $=2C$

$=8.68×10^{24}$ Particles

O$=4.34×10^{24}$ Particles

12.

Na $=2×6.022×10^{23}×0.32$

$=3.85×10^{23}$ Particles

C$=\frac{1}{2}$ of Na

$=1.93×10^{23}$ Particles

O$=3$ of C

$=3×1.93×10^{23}$

$=5.78×10^{23}$ Particles
