Discussion Overview

The discussion revolves around the concept of solution concentration, specifically whether a solution can have a weight/volume (w/v) concentration greater than 100%. Participants explore the conversion of a 75% g/g concentration to a w/v percentage and the implications of obtaining a value exceeding 100%.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant questions the validity of obtaining a concentration greater than 100% when converting from g/g to g/ml.
  • Another participant requests clarification on the formula used for calculating w/v concentration.
  • A participant provides a calculation that results in a w/v percentage of 107.5%, expressing confusion about the correctness of this result.
  • Another participant suggests that having a w/v percentage higher than 100% is not unusual and finds the calculated value acceptable, though they note uncertainty about the calculation process.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the interpretation of a w/v percentage greater than 100%. Some express confusion while others suggest it is acceptable.

Contextual Notes

The discussion includes unresolved questions about the assumptions underlying the calculations and the definitions of concentration types. Specific details about the calculation method and the properties of the solution are not fully clarified.

Homework Statement
Convert a solution 75% g/g (d = 1,4337) TO % g/ml
Relevant Equations
% g/ml = (gr solute / ml solution) * 100
Hello!
When I want to convert 75% g/g of a solution to % g/ml, I get a concentration greater than 100%. it is right?

is this possible?

It doesn’t make sense. What is your formula for W/V (g/vol)?

$$ w/v = \frac {w solute} {v solution} * 100$$
$$ w/v = \frac {75 g solute} {69,75 ml solution} * 100$$
$$ w/v = 107,5 % percent$$ :wideeyed:

what am I doing wrong?
