QuestionConvert $2.19 \mu \mathrm{g}$ of vitamin $\mathrm{B}_{12}$ $(cyanocobalamin) to milligrams ($ \mathrm{mg}$).

Studdy Solution

STEP 1

Assumptions1. The given amount of cyanocobalamin (vitamin B12) is $.19 \mu g$ . . We need to convert this amount to milligrams (mg).
3. The conversion factor from micrograms ( $\mu g$ ) to milligrams (mg) is $1 mg =1000 \mu g$ .

STEP 2

First, we need to write down the conversion equation. The conversion from micrograms to milligrams is done by dividing the number of micrograms by1000, because there are1000 micrograms in a milligram.
$Amount\, in\, mg = Amount\, in\, \mu g /1000$

STEP 3

Now, plug in the given value for the amount in micrograms to calculate the amount in milligrams.
$Amount\, in\, mg =2.19 \mu g /1000$

STEP 4

Calculate the amount in milligrams.
$Amount\, in\, mg =2.19 /1000 =0.00219 mg$ So, $2.19 \mu g$ of cyanocobalamin (vitamin B12) is equal to $0.00219 mg$ .
