A reading of what level in mg/l corresponds to .03% BAC?

To understand how a blood alcohol concentration (BAC) of 0.03% corresponds to a specific level in milligrams per liter (mg/l), we first convert the BAC percentage into a more concrete measurement.

A BAC of 0.03% means that there are 0.03 grams of alcohol per 100 milliliters of blood. Since 1 liter equals 1,000 milliliters, we can convert this value to milligrams per liter by following these steps:

1. Convert 0.03 grams to milligrams: 0.03 grams is equal to 30 milligrams (since 1 gram = 1,000 milligrams).

2. Since this amount is contained in 100 milliliters, we need to scale it up to 1 liter (1,000 milliliters), which means multiplying by 10 (because 1,000 ml is 10 times 100 ml).

This gives us:

30 mg * 10 = 300 mg/l.

To match this with the options given, it's evident there is an underlying misunderstanding in the question context or the available answer choices since none of them align with the calculated equivalent level of BAC for 0.03%.
