Verified step by step guidance1
Identify the given information: the number of moles of manganese (Mn) is 0.885 moles, and the atomic mass of Mn is 54.94 g/mol.
Recall the relationship between moles, molar mass, and mass: \(\text{mass} = \text{moles} \times \text{molar mass}\).
Set up the calculation using the formula: \(\text{mass} = 0.885 \text{ moles} \times 54.94 \text{ g/mol}\).
Multiply the number of moles by the atomic mass to find the mass in grams.
Express the final answer in grams, which represents the mass of 0.885 moles of manganese.
