V=abc
a = 2,3cm
b=12,2mm = 1,22cm
c = 0,75inch = 1,905cm
V = 2,3cm*1,22cm*1,905cm ≈ 5,35cm³
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
