Urea (CO(NH2)2) synthesis:

CO2 + 2NH3 ===> CO(NH2)2 + H2O

Given:

12.0 grams CO2
15.0 grams of NH3

After the reaction:

moles of CO2 = 12 grams / 44g/mol = 0.27 moles = 0.27/1 = 0.27
moles of NH3 = 15 grams/ 17g/mol = 0.88 moles = 0.88/2 = 0.44

The limiting reactant is CO2. Thus, we will base our calculations on the amount of CO2 available.

moles H2O produced = 0.27 moles CO2 * 1 mol/ 1 mol = 0.27 moles H2O
moles Urea produced = 0.27 moles CO2 * 1 mol/1 mol = 0.27 moles Urea


Total moles in the vessel = excess ammonia + H2O + Urea
                                           = (0.44 - 0.27) + 0.27 + 0.27
                                           = 0.71 moles

The mole fraction of water vapor in the reaction vessel is:

0.27 moles water vapor / 0.71 moles = 0.38 <span />

If the dosage for a medication is 225mg/lb, how many grams should a 25-lb child be given?
Oksanka [162]

Answer:

5.625 grams

Explanation:

Start your equation with what you have been given.  Place the units you need in your answer on the right side of the equal sign.

225mg

-----------   X  -----------   X ------------- =   ?   g

   lb

Now start to fill in your equation and use a conversions to get rid of the units you don't want.  Convert mg into grams first.  The child's weight (25 lb) is placed over 1 just to get the equation lined up properly so you can see how the units cancel out.

225 mg                 1 g                  25 lb            5.625 g

---------------   X   ---------------  X   -------------  =   ---------------

   lb                    1000 mg                 1                  1

The lb on the top and bottom cancel each other out and you are left with just grams.  Even though it is over one, that is the same at just 5.625 grams.
