36.0 g of Be contains how many moles? 0.25 mol 4.0 mol 45 mol 320 mol

## Step 1<br />The molar mass of Beryllium (Be) is approximately 9.0122 g/mol. This is the mass of one mole of Beryllium.<br /><br />## Step 2<br />To find the number of moles in 36.0 g of Be, we need to divide the given mass of Be by its molar mass.<br /><br />### **Number of moles = \(\frac{Mass}{Molar mass}\)**<br /><br />## Step 3<br />Substitute the given values into the formula:<br /><br />### **Number of moles = \(\frac{36.0 g}{9.0122 g/mol}\)**
