A patient receives 100ml of 24% (m/v) mannitol solution every hour
How many grams of mannitol are given in 1 hour?
Express your answer using two significant figures.
To find the number of grams of mannitol given in 1 hour, we need to determine the concentration of mannitol in the solution.
A 24% (m/v) mannitol solution means that there are 24 grams of mannitol present in every 100 milliliters of the solution.
Since the patient receives 100ml of the solution every hour, we can conclude that there are 24 grams of mannitol given in 1 hour.
Therefore, the patient receives 24 grams of mannitol in 1 hour.
To find the number of grams of mannitol given in 1 hour, we need to multiply the volume of the mannitol solution and the concentration of mannitol.
Given:
Volume of mannitol solution = 100 mL
Concentration of mannitol = 24% (m/v) = 24 g/100 mL
To calculate the number of grams of mannitol given in 1 hour, we can use the following formula:
Grams of mannitol = Volume of mannitol solution x Concentration of mannitol
Substituting the given values:
Grams of mannitol = 100 mL x (24 g/100 mL)
Grams of mannitol = 100 mL x 0.24 g/mL
Grams of mannitol = 24 grams
Therefore, in 1 hour, 24 grams of mannitol are given.
To find the number of grams of mannitol given in 1 hour, we need to multiply the volume of the solution (in milliliters) by the concentration of mannitol (in grams per milliliter).
Given:
Volume of mannitol solution = 100 ml
Concentration of mannitol solution = 24% (24 grams per 100 ml)
Step 1: Convert the concentration from percentage to decimal:
24% = 24/100 = 0.24
Step 2: Multiply the volume by the concentration:
Grams of mannitol = 100 ml x 0.24 g/ml
Step 3: Calculate the result:
Grams of mannitol = 24 g
Therefore, in 1 hour, 24 grams of mannitol are given.
