Determine the mass % (m/m) of a NaCl solution if 58.5 grams of NaCl was dissolved in 50 ml of water (assume the density of water to be 1.0 g/ml).
looks like 58.5/(58.5+50) = 53.9%
Ah, measuring mass percentages, eh? Well, let's dive into the salty math, shall we?
To determine the mass percentage, we need to calculate the mass of the entire solution. We start with 58.5 grams of NaCl and add that to 50 ml of water. But, before we do that, let's convert milliliters to grams, since we want everything in the same unit.
Since the density of water is 1.0 g/ml, 50 ml of water would be 50 grams. So, together with the 58.5 grams of NaCl, we have a total mass of 108.5 grams.
Now we divide the mass of NaCl by the total mass and multiply by 100 to get the mass percentage:
(58.5 grams / 108.5 grams) * 100 = 53.91%
So, the mass percentage of the NaCl solution is approximately 53.91%. Now you've got a salty answer to your question!
To determine the mass % (m/m) of a NaCl solution, we need to calculate the ratio of the mass of NaCl to the total mass of the solution, and then multiply it by 100.
Step 1: Calculate the mass of the NaCl
Given that 58.5 grams of NaCl was dissolved, the mass of NaCl is 58.5 grams.
Step 2: Calculate the total mass of the solution
To determine the total mass of the solution, we need to consider the mass of NaCl and the mass of water.
The density of water is 1.0 g/ml, and the volume of water is given as 50 ml. Therefore, the mass of water is:
Mass of water = Volume of water x Density of water
Mass of water = 50 ml x 1.0 g/ml
Mass of water = 50 grams
Step 3: Calculate the mass % (m/m) of NaCl
Mass % (m/m) = (Mass of NaCl / Total mass of solution) x 100
Mass % (m/m) = (58.5 grams / (58.5 grams + 50 grams)) x 100
Mass % (m/m) = (58.5 grams / 108.5 grams) x 100
Mass % (m/m) = 0.539 x 100
Mass % (m/m) = 53.9%
Therefore, the mass % (m/m) of the NaCl solution is 53.9%.
To determine the mass % (m/m) of a NaCl solution, we need to calculate the ratio of the mass of NaCl to the total mass of the solution.
First, we calculate the mass of water:
Mass of water = volume of water x density of water
Mass of water = 50 ml x 1.0 g/ml
Mass of water = 50 grams
Next, we calculate the total mass of the solution:
Total mass of solution = mass of NaCl + mass of water
Total mass of solution = 58.5 grams + 50 grams
Total mass of solution = 108.5 grams
Now, we can calculate the mass percent (m/m) of NaCl in the solution:
Mass % (m/m) of NaCl = (mass of NaCl / total mass of solution) x 100%
Mass % (m/m) of NaCl = (58.5 grams / 108.5 grams) x 100%
Mass % (m/m) of NaCl = 0.539 x 100%
Mass % (m/m) of NaCl = 53.9%
Therefore, the mass % (m/m) of NaCl in the solution is 53.9%.
