According to the table above, how many electrons are needed to have a combined mass of 1.0465 x 10^-25 kg?

• A. 2.1028 x 10¹³
• B. 1.1500 x 10⁵
• C. 8.8192 x 10²⁵
• D. 3.2235 x 10²²

Answer: (B)

Verified step by step guidance

1. Identify the mass of a single electron. The mass of an electron is approximately 9.109 x 10^-31 kg.
2. Set up the equation to find the number of electrons needed to reach the given mass. Use the formula: \( \text{Number of electrons} = \frac{\text{Total mass}}{\text{Mass of one electron}} \).
3. Substitute the given total mass (1.0465 x 10^-25 kg) and the mass of one electron (9.109 x 10^-31 kg) into the equation.
4. Perform the division to calculate the number of electrons: \( \frac{1.0465 \times 10^{-25}}{9.109 \times 10^{-31}} \).
5. Analyze the result to determine which of the provided options matches the calculated number of electrons.
