if 12.8g of NaCl is added to 243.2 mL of water (density (1.00g/mL)). the volume occupied by the solution is 250.0 mL. Calculate the density of the salt water.
Volfor nacl(solute)=v of solution - v of water(solvent
=250.0 - 243.2
= 6.80mL
Density (salt )= mass/ volume
=12.8/6.80
=1.88 g/mL
density salt water = mass salt water/volume salt water.
mass salt water = 243.2 + 12.8 = 256.0 g.
volume salt solution = 250.0
density = mass/volume = 256.0/250.0 = 1.02 g/mL
22,342
1.99 is not right.
22,342 is not right.
24.332
I should have said 1.88 is not right.
24.332 is not right either. If you want to show your work I'll find the error for you. You would need over 6000 grams NaCl in 250 cc solution to have a density of over 24.
To calculate the density of the saltwater solution, we first need to find the total mass of the solution.
The mass of the NaCl added to the water is given as 12.8 grams. The density of water is given as 1.00 g/mL. So, the mass of the water in the solution can be calculated by subtracting the mass of NaCl from the total mass of the solution.
Mass of water = Total mass of solution - Mass of NaCl
To find the total mass of the solution, we need to convert the volume of the solution to grams using the density of water.
Total mass of solution = Volume of solution × Density of solution
Given that the volume occupied by the solution is 250.0 mL, we can calculate the mass of the solution.
Mass of solution = 250.0 mL × 1.00 g/mL
Once we have calculated the mass of the solution, we can subtract the mass of NaCl to find the mass of water.
Mass of water = Mass of solution - Mass of NaCl
Finally, we can divide the mass of water by the volume of the solution to obtain the density.
Density = Mass of water / Volume of solution
By plugging in the values, we can calculate the density of the saltwater solution.
