Question

calculate the number of mole in 27g of Al

Answer 1

Explanation:

How many atoms are there in 27g of aluminum? the molar mass of the substance for aluminum = 26.98. the mass in gram / the molar mass of the substance. 27/26.89=1.0007 = 1.01 mol.

Answer 2

Given - Mass of Aluminium

Find - Number of moles

Solution - The number of moles in 27 grams of aluminium is 1.

The number of moles can be calculated by the formula = mass/molar mass.

The molar mass of aluminium is 27 gram/mole

Keep the values in the formula to find the number of moles.

Number of moles = 27/27

Number of moles = 1

Thus, the number of moles in 27 grams of aluminium is 1.
