B
Add 1.24 moles to the molar mass of beryllium (9.01 g/mol).
C
Multiply 1.24 moles by the molar mass of beryllium (9.01 g/mol).
D
Divide 1.24 moles by the molar mass of beryllium (9.01 g/mol).
Verified step by step guidance1
Identify the given information: You have 1.24 moles of beryllium, and the molar mass of beryllium is 9.01 g/mol.
Understand the concept: The mass of a substance can be calculated using the formula: \( \text{mass} = \text{moles} \times \text{molar mass} \).
Set up the calculation: Use the formula \( \text{mass} = \text{moles} \times \text{molar mass} \) to find the mass in grams.
Substitute the values into the formula: \( \text{mass} = 1.24 \text{ moles} \times 9.01 \text{ g/mol} \).
Perform the multiplication to find the mass in grams, which will give you the mass of 1.24 moles of beryllium.
