Final answer:
Yes, you can have 5 x 10^-25 g of Al.
Step-by-step explanation:
The atomic mass of Al is given as 26.98154 g/mol. To determine if you can have 5 x 10^-25 g of Al, we need to convert this value to moles. To do this, we can use the molar mass of Al as a conversion factor. The molar mass of Al is 26.98 g/mol (rounded to two decimal places).
Using the conversion factor, we can calculate the number of moles:
Number of moles = Mass of Al / Molar mass of Al = 5 x 10^-25 g / 26.98 g/mol = 1.852 x 10^-26 mol
Since we have obtained a non-zero value for the number of moles (1.852 x 10^-26 mol), we can conclude that you can have 5 x 10^-25 g of Al.
