1kg x 230lbs 2.2lbs Cancel out the lbs and divide 230 by 2.2 and get 104.5 kg 2tabs x 250mg x 1gm =gm 1tab x 1000mg tabs and mg cancels out. Reduce 250 to 1, and 1000 to 4. reduce the left over 2/4 to 2grams. I am left with 2grams and 104.5kg, but I don't understand what to do from this point on.

104.5kg and she takes two 250mg tablets a day. 500mg (2 tabs of 250mg) in grams is 0.5 grams. So 0.5 grams divided by 104.5 = 4.78 I can't see the rounding instructions, but is that the way to go about that problem?

How much calcium is present in the patients 3L on blood. Calcium is measured in the problem in mg, and the answer needs to be in grams. 8.3mg x 3L divided by 1000. 0.0249 grams.

The last one I think it is asking for me to find the gm/kg. I have 2.2kb / 230lb = 104.5kg Then 2tabs x 250mg x 1gm = grams 1tab 1000gm =2 grams Then I am confused as to what is next.

I see that the second to last problem needs grams of calcium, and they forgot to convert mg to grams. Would it be? 3L x 8.3mg x 1gm = grams 1 1L 1000mg =40grams?

Howdy! My friend asked for some help with dosage calculation problems, but the format of the last two questions are throwing me off. Could anyone give me a hand setting up these problems please?
