how many l are there in 450 ml? 450 ml = ? l give your answer in standard form.

Explanation:

Step1: Recall the conversion factor

We know that 1 L = 1000 mL.

Step2: Set up the conversion

To convert 450 mL to L, we divide 450 by 1000, so the calculation is $450\div1000$.

Step3: Perform the division

$450\div1000 = 0.45$. In standard - form, $0.45=4.5\times10^{- 1}$.

Answer:

$4.5\times10^{-1}$ L
