SUMMARY

The discussion centers on a chemistry homework problem involving a 65.0 cm³ sample of plumber's solder, a lead-tin alloy with 67% lead (Pb) by mass and a density of 9.4 g/cm³. Participants suggest calculating the mass of lead and tin in the sample as a starting point. The urgency of the submission deadline, set for 11 PM on April 19, 2009, is emphasized, highlighting the need for prompt assistance.

PREREQUISITES
  • Understanding of density calculations in chemistry
  • Knowledge of mass percentage composition
  • Familiarity with atomic mass units
  • Basic skills in unit conversion
NEXT STEPS
  • Calculate the mass of lead and tin in the solder sample
  • Determine the total mass of the 65.0 cm³ sample using density
  • Convert mass of lead and tin to moles using atomic weights
  • Calculate the total number of atoms in the sample
USEFUL FOR

Students studying chemistry, particularly those working on problems involving alloys, density, and atomic calculations.

hi everyone, i have this homework problem that I'm trying to solve. please help me with this cux I am not good at chem and I'm really stucked and i need to submit this problem online tomorrow ( 04/19/09 by 11pm .thanks a bunch for your help.


How many atoms are present in a 65.0cm^3 sample of plumber's solder, a lead–tin alloy containing 67% Pb by mass and having a density of 9.4 g/cm^3?

Welcome to PF.

I don't know in which time zone you are (it's now 10:20 am here) but that's not a lot of time you have left.

You could start by calculating how many grams of lead and how many grams of tin you have.
