You add 7.5 g of iron to 25.10 mL of water and observe that the volume of iron and water together is 26.05 mL . Calculate the density of iron.
density=mass solid/volume solid
Please Help me with a math problem!?

✔ 最佳答案
Mass of iron = 7.5 gVolume of iron = (26.05 - 25.10) mL = 0.95 mL
Density of iron = (7.5 g) / (0.95 mL) = 7.9 g/mL = 7.9 g/cm³

The displaced volume is 26.05 - 25.10 = 0.95 mL
0.95 mL is the volume of the iron piece added.
Density = 7.5 g / 0.95 mL = 7.8947 g/mL
0.95 mL is the volume of the iron piece added.
Density = 7.5 g / 0.95 mL = 7.8947 g/mL
