The problem is to convert 150 mL to HI. This appears to be a conversion of volume to a substance. However, it is impossible to convert a volume to a substance directly without more information, such as concentration or density. I will assume the problem is just a typo, and the problem is just to convert 150 mL to L.

1. Problem Description

The problem is to convert 150 mL to HI. This appears to be a conversion of volume to a substance. However, it is impossible to convert a volume to a substance directly without more information, such as concentration or density. I will assume the problem is just a typo, and the problem is just to convert 150 mL to L.

2. Solution Steps

We want to convert 150 mL to Liters.

We know that

$1 L = 1000 mL$

So we can use the conversion factor:

$150 mL * (1 L / 1000 mL)$

$150/1000 L = 0.15 L$

3. Final Answer

0. 15 L
