All multiple parts to the same problem, thank you! :)
Solution Stoichiometry: We need to make a 0.250 M sodium carbonate solution. We will use a 100.00 mL volumetric flask. How many grams of solid sodium carbonate should we add to the flask to make the solution? Use 105.99 as the molar mass, report correct sig figs, and use g as the unit. Solution Stoichiometry: We need to make a 0.200 M calcium chloride solution. We will use a 100.00...

8 Use the information and examples provided in the Exploration to calculate how many moles of CaCh+2H20 are present in 150 g of CaCly 2H20 and then calculate how many moles of pure Cach are present in the 1.50 g of CaCl 2H2O. Record the answers in Data Table 1 Use the information and examples provided in the Exploration (and values input into Data Table 1, in step 8) to determine how many moles of Nazco, are necessary...

Solution Stoichiometry: The next step in the lab is to carefully measure out 25.00 mL of the 0.250 M Na2CO3 solution, and 30.00 mL of the 0.200 M CaCl2 solution, and mix them together. Use Reaction Stoichiometry to predict the limiting reactant in the reaction, and the amount in grams of calcium carbonate that we expect to precipitate (theoretical yield). Remember: M= mols solute / L solution Use the following table to help organize your information. 0.250 M Na2CO3 00.200M...

The example given the following problem:
I used 1.50 grams of the
CaCl2•2H2O.
I just want to make sure I did my calculations right?
Could someone please review my answers and provide appropriate
feedback my their answers to mine differ?
If they do, can you show your work.
A step-by-step example of this process, using the balanced equation from Figure 1, is shown below: CuSO4(aq)2NaOH(aq) -> Cu(OH)2(s) Na2SO4(aq) Assuming there are only 5.70 grams of CuSO4 available, how many grams...
