How many g of amino acids are in a 2,000mL total parenteral nutrition of 4.25% travesol (amino acids and 20%dextrose?
kirill115 [55]

Answer:

The  mass of  amino acid present is  85 g

Step-by-step explanation:

From the question we are told that

   The  volume of the total  parenteral nutrition is  V  =  2000 mL

   

Generally the volume of the amino acid present is  

                V_a =  0.0425 *  2000

                V_a =  85 mL

Generally  

               mass  \ \ \alpha  \ \ volume

So the mass of amino acid present is 85g

I really need help please!! <br><br> ax - b = c<br><br> Solve for X<br><br> Show work please!!
Elina [12.6K]

ax - b = c

add b to both sides

ax - b + b = c + b

simplifying

ax =  c + b

divide both sides by a

ax / a =  (c + b) / a

simplifying

x =  (c + b) / a

You need to find what 34 is 25% of.

I personally would take 34 and divide it by .25 (25%) to get your answer and then to double check it, multiple the answer you get by 25%

34 \div .25 = 136
136 \times .25 = 34
so originally the farmer had 136 kg of apples of I'm not mistaken.
