9 grams aluminum (1 mole Al/26.98 grams) = 0.3 moles aluminum ==============
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.
9g of sugar would have more molecules than 9g of water because sugar molecules are larger and heavier than water molecules. This means that for the same weight, there would be fewer sugar molecules compared to water molecules.
To find the mass of 3.5 x 10^22 molecules of CO2, we need to multiply the number of molecules by the molar mass of CO2. The molar mass of CO2 is approximately 44 grams per mole. So, 3.5 x 10^22 molecules of CO2 would have a mass of approximately 1.54 x 10^25 grams.
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).
9 grams aluminum (1 mole Al/26.98 grams) = 0.3 moles aluminum ==============
In 9g of H2O, there are approximately 3.01 x 10^23 molecules of water. Each water molecule contains 2 covalent bonds - one between the oxygen and each of the hydrogen atoms. So, there are a total of 6.02 x 10^23 covalent bonds present in 9g of H2O.
9g+9
49-9g = 40
9g-142g = -133
It is: 12g+9g = 21g
9g = 0.317oz
(9g - 8)(9g + 8)

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.
