Determine the mass (in grams) of one mole of calcium atoms. Give the answer to two decimal places (no unit required).
Question
Determine the mass (in grams) of one mole of calcium atoms.
Give the answer to two decimal places (no unit required).
Solution
Step 1: Break Down the Problem
To find the mass of one mole of calcium atoms, we need to refer to the molar mass of calcium, which is typically found on the periodic table.
Step 2: Relevant Concepts
The molar mass of an element is the mass of one mole of its atoms and is expressed in grams per mole (g/mol). Specifically, for calcium (Ca), we look up its atomic weight.
Step 3: Analysis and Detail
The atomic weight of calcium is approximately 40.08 g/mol. This value represents the mass of one mole of calcium atoms.
Step 4: Verify and Summarize
Confirming the atomic weight from a reliable periodic table shows that the value is accurate.
Final Answer
40.08
