How many mole of atoms are there in 9g of Aluminium?

To find the number of moles of atoms in 9 grams of aluminum, you can use the molar mass of aluminum, which is approximately 27 g/mol. Dividing the mass of aluminum (9 g) by its molar mass (27 g/mol) gives you about 0.33 moles of aluminum. Since each aluminum atom is a single atom, there are also 0.33 moles of atoms in 9 grams of aluminum.


Which one has more molecules in 9g of water or 9g of sugur?

There are more molecules in 9g of water than in 9g of sugar. This is because the molecular weight of water is lower than that of sugar, so there are more water molecules present in the same mass as sugar.


How one has more molecules 9g of water or9g of sugar?

Perhaps you mean: Does sugar have more atoms than water?In a certain fixed mass of sugar/water, there will be more molecules of water than of sugar since the molecular mass of sugar is higher than that of water. We follow the rule of Mass = Number of moles of a substance * Molecular mass of the substance.We rearrange this to form Number of moles = Mass / Molecular massTherefore, since the molecular mass of sugar is higher, the number of moles of sugar in a fixed mass of sugar is lower. The number of moles of sugar is directly proportional to the number of molecules of sugar, since we follow Avogadro's Law:1 mole = 6 * 10^23 molecules (constant value)However, if you meant to ask if sugar had more atoms than water, the answer is yes, it does. Sugar (presumably glucose) has the chemical formula of C6H12O6 and thus has 24 C, H and O atoms altogether. Water, with the formula H2O, has 3 atoms of H and O altogether.I hope this was helpful! :)


How can you prepare 50mm glucose?

To prepare a 50mm glucose solution, you would need to dissolve 9g of glucose in enough water to make 100mL of solution. This would give you a solution with a concentration of 50mm (millimolar).


Which is bigger 2000 nanogram or 200 microgram?

2000 nanograms is equal to 2000 x 10-9g. Moving some zeroes, this equals 2 x 10-6g, or 2 micrograms. So 200 micrograms is larger.
