Calculate number of moles of aluminum in 1.50kg of Al

moles = grams/molar mass. Convert 1.50 kg to grams = 1,500 grams.

To calculate the number of moles of aluminum (Al) in 1.50 kg of Al, we need to use the molar mass of aluminum.

The molar mass of aluminum (Al) is 26.98 g/mol.

First, we need to convert the mass of aluminum from kilograms to grams:

1.50 kg = 1500 g

Next, we can use the molar mass to calculate the number of moles:

Number of moles (n) = mass (m) / molar mass (M)

n = 1500 g / 26.98 g/mol

n ≈ 55.6 mol

Therefore, there are approximately 55.6 moles of aluminum in 1.50 kg of Al.

To calculate the number of moles of aluminum in 1.50 kg of Al, you need to use the molar mass of aluminum and the formula:

Number of moles = Mass of substance (in grams) / Molar mass

The molar mass of aluminum (Al) is 26.98 g/mol, so:

Number of moles = 1.50 kg * 1000 g/kg / 26.98 g/mol

First, you need to convert kilograms (kg) to grams (g) by multiplying by 1000 since there are 1000 grams in 1 kilogram.

Number of moles = 1500 g / 26.98 g/mol

Now divide the mass (in grams) by the molar mass to get the number of moles:

Number of moles = 55.59 mol (rounded to two decimal places)

Therefore, there are approximately 55.59 moles of aluminum in 1.50 kg of Al.
