How is fehling's solution prepared?
fehling's solution is dark blue at room temperature "Fehling's solution" is prepared by dissolving separately 34'639 grammes of copper sulphate, 173 grammes of Rochelle salt, and 71 grammes of caustic soda in water, mixing and making up to l000 ccs.; 10 ccs. of this solution is completely reduced by o 05 grammes of hexose
If a solid has a molar mass of 208 g per mol after being heated how many formula units of water are there in one formula unit of the unheated compound?
Moles of the soild = 1.78/ 208 = .00856 moles of H2O = 0.90/ 18 =.05 therefore number of moles of water for 1 mole of solid = .05/.00856 = approx 6
Is 05 a solution to 5x-3y15?
If you are asking if x=0, y=5 is a solution to 5x-3y=15, then no. 0, -5 would be as if you sub in 0 for x you get 5(0) -3y=15, i.e. -3y=15, i.e. y=-5
How much mass of sucrose is needed to make 50ml of a 1.75M sucrose solution?

What is molarity of 5 percent acetic acid?
(.05)X(grams of total solution) = grams of acetic acid (grams of acetic acid)/ (mol. wt. of acetic acid(=60g/mol)) = mol. acetic acid (mol. acetic acid)/ (Liters of total solution) = molarity(M)

What is the clock time 5 after 4?

8. On most periodic tables a single atomic mass is listed instead of the mass numbers for all the stable isotopes. How is this mass related to the different isotopes?
In a normal periodic table, the molar mass of a given element, is made up of multiplying the mass of a given isotope of that element, with the abundance of that given isotope in percent. For example, Say for the element X, you know that it has two isotopes, X12 and X13. X12 has a molar mass of 12 g/mol, and you know that of all the X molecules in the world, X12 is found 95% of the time, X13 has a molar mass of 13g/mol, yet its abundence is only 5%. Therefore average molar mass for element X is calculated as such, (12 * .95)+(13*.05) = 12.05 g/mol. hope that helps.
