Solute - sucrose (minority) + Solvent water (majority) = Solution
In this concentration series lab, the solute is sucrose C12H22O11, the solvent is water H2O
I used 57g or 4 tablespoons of sucrose (C12H22O11) with a g/mol of 342 and divided the two units
Serial dilution of sucrose C12H22O11
Purpose: The purpose of this lab is to dilute the Mother solution down to 0.000001M (PPM)
Materials: Sucrose C12H22O11/ Water H2O
Procedure: Serial dilution
Data (20 pt): (Remember units and sig figs!)

I. The Chemical Equation
A. What is a chemical reaction?
In a chemical reaction, the starting materials (atoms,
molecules, ions) break bonds and form new bonds making
new substances called products. For example, when small
