Step 1:Let's solve this step by step:
Step 2:: Understand the given information
- We need to find the number of electrons in 1 atomic mass unit (amu) - Mass of one electron is 0.00054 amu
Step 3:: Calculate the number of electrons in 1 amu
\frac{1 \text{ amu}}{0.00054 \text{ amu per electron}} = \text{Number of electrons}
- To find the number of electrons, we'll divide 1 amu by the mass of a single electron
Step 4:: Perform the calculation
\frac{1}{0.00054} = 1,852
Step 5:: Verify the result
- This matches option (c) 1852 electrons
Step 6:: Double-check the reasoning
- We divided the total mass (1 amu) by the mass of a single electron - This gives us the number of electrons needed to make up 1 amu
Final Answer
Key Insights: - The calculation is a simple division - Always pay attention to the units when solving such problems - Carefully read the given information and match the result to the provided options
