The complete question is: Calculate the volume in milliliters of a 1.72 mol/L sodium thiosulfate solution that contains 375. mmol of sodium thiosulfate (Na_2S_2O_3).Round your answer to 3 significant digits.
Answer:
218 mL
Explanation:
Using C = n/V
Where n = number of mole
C = concentration in mol/L
V= Volume
Given: n = 375 mmol
= 0.375mol
C = 1.72mol/L
From the formula: V = n/C
= 0.375/1.72
= 0.21802L
Multiplying by 1000 gives 218 mL
