Reread the "DataAnalysis" section if necessary for complete understanding.Density of water using the graduated cylinder (nchude proper units):89.83mLDensity of water using the buret (include proper units):90.24mL2. Which measuring device would you use if you needed to know the volume of a liquid veryprecisely? Why?When you need to know the exact amount of a liquid, my partner and I believe that a graduatedcylinder is the greatest measurement tool to utilize. The graduated cylinder was chosen because ofthe small tick marks in between the big numbers, which provide scientists and ordinary peoplewith an accurate yet precise reading of the volume of liquid they are looking for.3. Using the data from the Trials with Graduated Cylinder (Trial 1) divide the mass recorded bythe volume of H;O. Show the work and be sure to use units and the appropriate significantfigures. What is the answer? Explain why this is not the density of water!99.210g/8mL = 12.40g mL. This is not the density of water because4. From the equation: m =DV the intercept value appears to be zero, which makes sense becauseif there is no volume, the mass of the liquid will be zero. Look at graph 2 (Buret) and determinethe "y intercept" both visually and mathematically.

scaling up Solutions Sometimes we know the concentration of a solute but we need to make a larger volume of the solution. Example: An IV saline solution is based on 0.9% NaCI = 0.9g/100mL (dL). To make 1L of the same concentration (0.9%), how many grams of NaCl would we need? Hint: first convert mL or dL to L. Next, to get from our original volume of 0.1 L to our desired volume of 1L, we need to multiply by a factor of 10. If we want to keep the concentration of this solution the same (0.9%) we will also need to multiply the amount of solute by the same factor of 10. Molar Ratios and Chemical Equations The concept of the mole is useful in chemical reactions. Molecules react in molar ratios which are expressed in equations. Neutralization of an Acid Example: HCI + NaOH → NaCI + H2O This equation says that 1 mole of acid is neutralized by 1 mole of base to produce 1 mole of salt and 1 mole of water. Since a mole is the MW in grams, then you can calculate how much base you need to to…
