You need to make 100 mL of a 0.05 mole solution of NaCl (formula weight 58.44 g/mol). How many grams NaCl do you need? How do you convert from amount of substance in moles to the number of atoms in an element? How many milliliters are in 30 liters?
Here, we multiply the concentration value in cell C5 by 10-6 to convert from μmol/liter to mol/liter. Press ENTER to get the pH value for solution A in cell D5. Use the Fill Handle tool to copy the formula to other cells. Determining Solution Type Click on cell E5 and enter the...
Here we are given the volume of the water in mL (milliliters), and we need to figure out how many molecules are present. We shall go through a...Become a member and unlock all Study Answers Start today. Try it now Create an account...
V = CYL_DISP = the displacement of one cylinder (in liters), R = 8.3143510 J/mol K, and T = (IAT-32)* 5/9 + 273 to convert IAT from °Fahrenheit to Kelvin. Note that we can combine the constants R and MMair into one, and we will ignore them from this point on since they...
Just remember that if a value is given for a reaction in one direction, if you flip the reaction around in the reverse direction you have to change the sign from positive to negative. (For example, if you have Na(s) -> Na(g) = 107.3 kj/mol, Na(g) -> Na(s) = -107.3 kj/...

H2SO4 + MgCl2 -> 2 HCl + MgSO4 Reaction Yield: The reaction yield refers to the process of calculating the amount of product that will be obtained from a chemical reaction, considering the amount of reagents that will participate in it. Depending of the ...
of the solution in liters. For example, the molarity of a 0.6 moles of NaCl dissolved in 0.45 liters is 1.33 M (0.6 mol ÷ 0.45 L). Do this for both substances to let you calculate the final concentration of the solution. (Remember 1.33 M stands for 1.33 mol/L and not 1.3 moles...
