The density of the liquid is about 1.85 g/mL.
Density is mass/volume. The volume is given (45.2 mL). The mass must be found by subtracting the tare weight of the graduated cylinder from the total:
95.1 g- 11.4g = 83.7g
Using the mass and volume of the liquid, you can now calculate the density:
d = m/v = 83.7g/45.2 mL = 1.8517699115 g/mL.
Of the original values, the least number of significant figures are 3, so the answer must have a degree of accuracy of 3 significant figures:
1.8517699115 g/mL ≈ 1.85 g/mL.
0.02375 moles
Explanation:
Fe2O3+CO :. Fe+CO2
We know that
56*2+16*3=160 gm of Fe2O3 can give 56 gm of Fe
So
3.8 gm can give 1.33 gm of Fe
It is equal to 1.33/56 moles of Fe which is equal to 0.02375 moles
They are rocks formed by different layers and all of which are different such as slate and are all attacked together to form a quite huge one.
This can happen by Earth's Heat.
