Quizplus · Accepted Answer

To calculate the kcalories provided by the 1000 mL of 50% dextrose solution, we need to multiply the volume in milliliters by the percentage of dextrose as a decimal (0.5) and then by the conversion factor of 3.4 kcal/g (the approximate number of kcalories per gram of dextrose).

Therefore, the calculation is:

1000 x 0.5 x 3.4 = 1700 kcalories

So the correct answer is B, which corresponds to "1700".
