Question

question 3
a volumetric flask contains 250.00 ml solution. what is the volume of this solution in units of liters?
2.5×10⁵ l
2.5000×10⁵ l
0.25000l
0.25 l

Explanation:

Step1: Unit conversion relationship

We know that \(1\space L = 1000\space mL\), so \(1\space mL=\frac{1}{1000}\space L = 10^{- 3}\space L\).

Step2: Convert \(250.00\space mL\) to \(L\)

Let \(V\) be the volume in liters. Using the conversion factor, \(V = 250.00\times10^{-3}\space L\).

$$V=\frac{250.00}{1000}\space L=0.25000\space L$$

Answer:

C. \(0.25000L\)
