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

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