Discussion Overview

The discussion revolves around identifying the element M in the compound MF6, which contains 32.38% fluorine (F) by mass. Participants explore the problem within the context of chemistry, specifically focusing on mass percentage calculations and the implications for determining the identity of M.

Discussion Character

  • Homework-related
  • Mathematical reasoning
  • Conceptual clarification

Main Points Raised

  • One participant expresses uncertainty about how to approach the problem and requests tips for solving it.
  • Another participant provides an analogy involving a fruit basket to illustrate the concept of mass percentage, suggesting that the mass of the unknown fruit (M) can be determined from the known mass of the apples (F).
  • A participant claims to have calculated the mass of M as 238.04 and suggests that this corresponds to uranium, asking for verification of this conclusion.
  • A moderator requests that the participant show their work to facilitate further assistance.

Areas of Agreement / Disagreement

There is no consensus on the identity of M, as participants have not fully verified the calculations or discussed the implications of the proposed solution. Multiple viewpoints and approaches to the problem remain present.

Contextual Notes

Participants have not provided detailed calculations or assumptions underlying their claims, and the discussion lacks clarity on the definitions of M, F, and MF6.

What is identity of M?

The Attempt at a Solution



I really have no idea how to start...sorry. If someone can give me tips, on how to do it, that way I can learn. Thanks!

What have you learned in Chem so far?

Do you know what M, F and MF6 are?

Here's a push in the right direction.

I have one large fruit of unknown type and unknown mass, and six apples in my (massless) fruit basket.
I know how much the apples mass individually, and I've been told that, together, they comprise 32.38% of the mass of my entire fruit basket.
The remaining % of the fruit basket is going to be the mass of the mystery fruit.

Wait I got 238.04 which would be Uranium right M=Uranium. If you can just verify this.
