Mass of an atom of Uranium is `3.7xx10^(-25)` kg. What will be its value in order of magnitude?

Options

A. `10^(-25)`
B. `10^(-24)`
C. `10^(-22)`
D. `10^(23)`

Explanation

To find the order of magnitude of the mass of an atom of Uranium given as \( 3.7 \times 10^{-25} \) kg, we follow these steps:

### Step-by-Step Solution:

1. **Identify the Scientific Notation**: The mass of the Uranium atom is given in scientific notation as \( 3.7 \times 10^{-25} \) kg.

2. **Focus on the Power of 10**: In scientific notation, the order of magnitude is determined by the exponent of 10. Here, the exponent is \(-25\).

3. **Determine the Order of Magnitude**: The order of magnitude is simply the exponent of 10 when the number is expressed in scientific notation. Therefore, the order of magnitude for \( 3.7 \times 10^{-25} \) kg is \(-25\).

4. **Final Answer**: The order of magnitude of the mass of an atom of Uranium is \( 10^{-25} \).
