Calc. the MM from decay and half life

Click For Summary

Discussion Overview

The discussion revolves around determining molar mass using half-life, decay rate, and mass of matter. Participants explore the relationship between these variables and how they can be utilized in calculations, focusing on both theoretical and practical aspects.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant expresses confusion about how to determine molar mass with the given parameters of half-life, decay rate, and mass.
  • Another participant suggests that more specific details are needed to address the question effectively.
  • Gokul proposes that if decay is measured in counts per minute, it is possible to calculate the number of atoms in the sample, which can lead to determining the molar mass.
  • A later reply by Gokul emphasizes that the initial decay rate and initial mass are crucial for solving the problem.

Areas of Agreement / Disagreement

Participants do not reach a consensus, as there are differing views on the sufficiency of the provided data and the approach to solving the problem.

Contextual Notes

The discussion highlights the need for clarity in the definitions of decay rate and mass, as well as the assumptions regarding initial conditions that may affect the calculations.

howdy,
how can one determine molar mass when the half life and dacay rate (d/min) and mass of matter are known? I am really puzzled. thanks for the help.

Please post the exact question and your thoughts. As of now, there's insufficient data.
 
Gokul: if the decay is defined as counts/minute there is enough data to solve the question :smile:

Calculate number of atoms in the sample that shows known number of decays per minute. You know the number of atoms, you know number of moles. Ready.

It would be appropriate to post the exact form of the question.

True (if the decay rate and mass are the "initial decay rate" and the "initial mass").
