Discussion Overview

The discussion revolves around calculating the mass of a solution given its density and the mass of a solute (CsCl) used to prepare it. Participants explore the relationship between density, volume, and mass in the context of a homework problem.

Discussion Character

  • Homework-related

Main Points Raised

  • One participant states the density of the solution is 1.182 g/mL and questions how to find the mass of the solution, initially suggesting it might just be the mass of the solute (185 grams).
  • Another participant asks how many grams of solution are in 1 liter, given the density.
  • A subsequent post reiterates the calculation, suggesting that multiplying the density by the volume (1.182 g/mL * 1000 mL) results in 1182 grams of solution.
  • A later reply confirms this calculation, indicating agreement with the previous statement about the mass of the solution.

Areas of Agreement / Disagreement

There appears to be a consensus on the calculation that the mass of the solution is 1182 grams, derived from the density and volume. However, initial confusion about whether the mass of the solution is simply the mass of the solute remains unaddressed.

Contextual Notes

Participants do not clarify the impact of the solute's mass on the total mass of the solution, nor do they discuss the assumptions involved in using density for this calculation.

Homework Statement



A solution is prepared by adding enough water to 185 grams of CsCl to form 1 liter of solution. What is the mass of the solution? The density of the solution is 1.182 g/mL.


Homework Equations



D= m/v

The Attempt at a Solution



D= 1.182 g/mL ----> 185 g CsCl / 1.182 g/ml = 156.5143824mL * 1L /1000L = 0.157L

but how do i find the mass? I am confused...? Isn't the mass of the solution just 185 grams?

If the density of the solution is 1.182 g/mL, how many grams of solution are in 1 liter of solution?

So you're saying if (1.182 g/mL)(1000ml/1L) = 1182 grams are in 1 liter of solution?

Actually that's what you said, Bohrok only asked :wink: But that's the correct answer.
