Average distance between water molecules

Click For Summary

Homework Help Overview

The discussion revolves around determining the average distance between water molecules at room temperature and pressure (rtp). Participants explore the relationship between water's density and molecular weight to derive relevant calculations.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants discuss the density of water and its molecular weight as a basis for calculating the number of moles in a given volume, questioning how these factors relate to the average distance between molecules.

Discussion Status

Some participants have provided calculations related to the density and molecular weight of water, while others emphasize the importance of adhering to forum rules by avoiding direct answers and instead encouraging hints and clarifications.

Contextual Notes

There is a reminder about the forum's rules against providing complete solutions to homework questions, highlighting the focus on guiding the original poster towards independent problem-solving.

Does anyone know what the average distance between water molecules at rtp is, or how I could work this out?

Thanks

Taking into account the density of water = 1 Kg/L = 1 g/cm3 and the molecular weight to be 18 g/mol then the number of moles found in unit volume is:

Welcome to the PF, huda123.

Please take care not to give out answers to homework/coursework questions. It is against the PF Homework Help rules. Please see the "Rules" link at the top of the page.

Please instead provide hints, or clarifying remarks, and be tutorial in your help here. Our goal is to help the original poster (OP) to figure out the problem on their own. After all, that is how they will learn the material the best.
