MOLE RATIO SCIENTIFIC OBJECTIVE: The main point of the experiment was to form a balanced chemical equation, the find the mole ratio. If a cloud of crystals had formed then when the two substances known as lead(II) nitrate and potassium dichromate were mixed at different doses measured in drops. with all of this being done it was about to show the mole ratio. The mole ratio the ratio of moles of what you've been given in a reaction to what you want to find. INTRODUCTION: A mole ratio is the ratio of moles of what you've been given in a reaction to what you want to find. for any scientific experiment involving moles a chemical equation would be needed. A chemical equation is a chemical reaction using symbols to represent specific elements from the periodic table. the coefficients are the numbers represent the number of moles of reactants and products. To put it simple the coefficients in the chemical equation balance it . The chemical equation used in the lab Pb(NO3)2 (aq) +K2Cr2O7 (aq) =PbCr2O7 (s) +2KNO3 (aq), this meant lead(II)+potassium dichromate equals lead(II)dichromate +potassium nitrate. A mole is the amount of pure substance containing the same number of chemical units as there are atoms. One of the main aspects connecting to a maloe is avogadro's number. This is the number of molecules in a mole of a substance. Avagadros number goes out to aproximately 602,250,000,000,000,000,000,000. A mole ratio is the ratio of moles of what you've been given in
