The density of a solution is calculated by dividing the mass of the solution by its volume. To determine which solution is denser, we need to compare their densities. The density of the 30ml solution is 1.5 g/ml (45g/30ml) while the density of the 40ml solution is 1.25 g/ml (50g/40ml). Therefore, the 30ml solution with a mass of 45g is denser than the 40ml solution with a mass of 50g.
The atomic mass of aluminum is approximately 26.98 atomic mass units.
To find the density of aluminum, you need a sample of aluminum, a scale to measure its mass, and a ruler to measure its volume. By dividing the mass of the aluminum by its volume, you can calculate the density of aluminum.
The mass of Avogadro's number of aluminum atoms is equal to the molar mass of aluminum, which is 26.98 grams/mol. This means that Avogadro's number of aluminum atoms has a mass of 26.98 grams.
Aluminum is a metallic element. It doesn't form molecules. Its atomic mass is 27u.

To find the mass of 0.25 moles of aluminum sulfate, you need to know the molar mass of aluminum sulfate. The molar mass of aluminum sulfate (Al2(SO4)3) is approximately 342.15 g/mol. Therefore, the mass of 0.25 moles of aluminum sulfate would be around 85.54 grams.
Aluminum's atomic mass is 26.9815386,but if rounded up,it is 27.
Density = Mass/Volume = 25/30 g/ml = 0.833... g/ml
The molar mass of aluminum is approximately 26.98 g/mol, so the mass of 1 mole of aluminum is 26.98 grams.
The molar mass of aluminum chloride (AlCl3) is 133.34 grams/mol.
To find the density of aluminum, you need a sample of aluminum, a scale to measure its mass, and a ruler to measure its volume. By dividing the mass of the aluminum by its volume, you can calculate the density of aluminum.
