You add 9.1 of iron to 25.50 of water and observe that the volume of iron and water together is 26.66 . Calculate the density of iron.
mass Fe = 9.1g.
I assume the volume is measured in cc.
volume Fe = 26.66cc-25.50cc = 1.66 cc.
Then density = mass/volume = ?
To calculate the density of iron, we need to know the mass and volume of the iron.
The mass of the iron can be calculated by subtracting the mass of the water from the total mass of iron and water.
Mass of iron = Total mass - Mass of water
To find the total mass, we add the masses of iron and water:
Total mass = Mass of iron + Mass of water
Given that you added 9.1 grams of iron to 25.50 grams of water, the total mass is:
Total mass = 9.1 g + 25.50 g
To calculate the volume of iron, we subtract the volume of water from the total volume of the iron and water.
Volume of iron = Total volume - Volume of water
To find the total volume, we add the volumes of iron and water:
Total volume = Volume of iron + Volume of water
Given that the volume of iron and water together is 26.66 mL, the total volume is:
Total volume = 26.66 mL
Now, we can calculate the density of iron using the formula:
Density = Mass / Volume
1. Calculate the mass of iron:
Mass of iron = Total mass - Mass of water = (9.1 g + 25.50 g) - 25.50 g
2. Calculate the volume of iron:
Volume of iron = Total volume - Volume of water = 26.66 mL - 25.50 mL
3. Calculate the density of iron:
Density of iron = Mass of iron / Volume of iron
By plugging in the calculated values from steps 1 and 2 into step 3, you can find the density of iron.
