SUMMARY

The discussion centers on the calculation of weight/volume (W/V) concentration, specifically converting a 75% g/g solution to a W/V percentage. The formula used is W/V = (w solute / v solution) * 100, which results in a calculated concentration of 107.5%. This indicates that it is indeed possible to have a W/V percentage greater than 100%, as demonstrated in the calculations presented. Participants confirm that the result is valid, despite initial confusion regarding the interpretation of such a concentration.

PREREQUISITES
  • Understanding of weight/volume (W/V) concentration calculations
  • Familiarity with the concept of mass percentage (g/g)
  • Basic knowledge of solution chemistry
  • Ability to perform unit conversions in chemistry
NEXT STEPS
  • Research the implications of W/V concentrations exceeding 100%
  • Learn about the differences between weight/volume and volume/volume concentrations
  • Explore the concept of solution saturation and its effects on concentration
  • Study the principles of solution preparation and dilution calculations
USEFUL FOR

Chemistry students, laboratory technicians, and professionals involved in solution preparation and analysis will benefit from this discussion.

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?
