Calculate the volume in milliliters of a sodium thiosulfate solution that contains of sodium thiosulfate . Be sure your answer has the correct number of significant digits.

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.

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
