How many grams (of mass m) of glucose are in 355mL of a 5.50% (m/v) glucose solution?
It is dilute, so assume the density is the same as water.
masssugar=355g*.0550
How many grams (of mass mm) of glucose are in 195mLmL of a 5.50%\% (m/v) glucose solution?
To find out how many grams of glucose are in a given volume of a glucose solution, you need to first understand the concept of percent concentration.
Percent concentration indicates the amount of solute (in this case, glucose) present in a given volume of solution. The formula for percent concentration is:
Percent Concentration (C) = (mass of solute / volume of solution) * 100
In this case, the percent concentration is expressed as a mass/volume percent (% m/v), which means grams of solute per 100 mL of solution.
Now, let's solve the problem step by step:
Step 1: Convert the given mL of solution to L.
355 mL = 355 / 1000 = 0.355 L
Step 2: Plug the given values into the percent concentration formula:
C = (mass of solute / volume of solution) * 100
Step 3: Rearrange the formula to solve for the mass of solute:
mass of solute = (C * volume of solution) / 100
Step 4: Calculate the mass of solute (glucose):
mass of solute = (5.50 * 0.355) / 100 = 0.019525 g
Therefore, there are approximately 0.019525 grams of glucose in 355 mL of a 5.50% (m/v) glucose solution.
