A graduated cylinder.measures 15.3 mL. Convert this measurement to DaL
ololo11 [35]

Answer:

0.000153DaL  

Explanation:

We have been given:

         15.3mL to convert to DaL

DaL is a unit of volume which indicates a decaliter.

 This implies that;

             1 Da L  = 1 x 10²L

So:

               1 mL  = 1 x 10⁻³L

       So 15.3mL will give 15.3 x 10⁻³L

So;

           1 x 10²L   =  1 DaL  

      15.3 x 10⁻³L  will give \frac{15.3 x 10^{-3} }{1 x 10^{2} }   = 15.3 x 10⁻⁵DaL

Therefore, this is 0.000153DaL
