How many moles are in 1800 grams of aluminum? 13.85 mol 6.672 mol 4856 mol 0.1499 mol

## Step 1To find the number of moles in a given mass of a substance, we use the formula:### **Number of moles = **In this formula, the mass is the given mass of the substance, and the molar mass is the mass of one mole of the substance.## Step 2The molar mass of aluminum (Al) is 26.98 g/mol. This is the mass of one mole of aluminum.## Step 3Substitute the given mass (1800 grams) and the molar mass of aluminum (26.98 g/mol) into the formula:### **Number of moles = **## Step 4Calculate the number of moles by performing the division:### **Number of moles = 66.72 mol**
