You have 0.01 mg of Manganese in 200 mL. How much do you have in 1L?

To determine how much manganese is present in 1 liter when you have 0.01 mg in 200 mL, you first need to establish how much manganese is in 1 mL and then scale it up to 1 liter (which is equivalent to 1000 mL).

Starting with the concentration of manganese in the given volume, you would calculate the concentration per milliliter as follows:

0.01 mg in 200 mL equates to: 0.01 mg / 200 mL = 0.00005 mg/mL

Next, to find out the total amount in 1000 mL (1 liter), you would multiply the concentration by the new volume: 0.00005 mg/mL * 1000 mL = 0.05 mg

This calculation shows that in 1 liter, there are indeed 0.05 mg of manganese. Therefore, this choice is the correct answer based on the given quantities and conversions between milliliters and liters.
