Calculate the number of grams of dextrose in 250mL of D5W.
I know that the answer is 12.5g, but I do not understand the work. Please help.
never mind... I got it! :-)
FYI--
(250 mL/1) * (5/100) = 12.5g
This is because D5W means dextrose in 5% water.
Hey there! So, to calculate the number of grams of dextrose in 250mL of D5W, we need to know the concentration of dextrose in D5W.
D5W stands for dextrose 5% in water. This means that there's 5 grams of dextrose in every 100 milliliters of solution.
Now, we have 250 milliliters of D5W, which means we'll have to find out how many grams of dextrose are in that amount.
To get the grams of dextrose, we can set up a simple proportion:
5 grams of dextrose / 100 milliliters of D5W = x grams of dextrose / 250 milliliters of D5W
Cross-multiplying, we have:
5 * 250 = 100 * x
1250 = 100x
Dividing both sides by 100:
12.5 = x
So, 250mL of D5W contains 12.5 grams of dextrose!
Hope that helps! If you have any more questions, feel free to ask, and I'll do my best to answer with a smile.
To calculate the number of grams of dextrose in 250mL of D5W (5% dextrose in water), you can use the following equation:
% concentration = (grams of solute/grams of solution) × 100
Since D5W is a 5% dextrose solution, it means that there are 5 grams of dextrose in 100mL of solution.
You can set up a proportion to calculate the number of grams of dextrose in 250mL:
5 grams/100mL = x grams/250mL
To solve this, you can cross-multiply and then divide:
100mL * x grams = 5 grams * 250mL
100x = 1250
x = 12.5 grams
Therefore, there are 12.5 grams of dextrose in 250mL of D5W.
To calculate the number of grams of dextrose in 250mL of D5W, we first need to understand what D5W is. D5W stands for Dextrose 5% in Water, which means it is a solution of 5% dextrose (or glucose) in water.
To calculate the number of grams, we need to find 5% of the total volume, which is 250mL.
Step 1: Convert the percentage to a decimal. To do this, divide the percentage by 100.
5% ÷ 100 = 0.05
Step 2: Multiply the decimal by the total volume in mL.
0.05 x 250 mL = 12.5 g
So, there are 12.5 grams of dextrose in 250 mL of D5W.
