(a)
Interpretation:
To write the scientific notation with two significant figures for 5100000 g.
Concept Introduction:
Scientific notation is a way to write a very large or very small numbers. In this type of notation, a number between 1 and 10 is multiplied by a power of 10.
The number of significant figures in an expression shows the precision of any measured number.
(b)
Interpretation:
To write the scientific notation with two significant figures for 26000 sec.
Concept Introduction:

(b) When do you need to perform back titration? (c) Ni2+ can be analyzed by a back titration using standard Zn2+ at pH 5.5 with xylenol orange indicator. A solution containing 25.00 mL of Ni2+ in dilute HCl is treated with 25.00 mL of 0.05283 M Na2EDTA. The solution is neutralized with NaOH, and the pH is adjusted to 5.5 with acetate buffer. The solution turns yellow when a few drops of indicator are added. Titration with 0.02299 M Zn2+ requires 17.61 mL to reach the red end point. What is the molarity of Ni2+ in the unknown?arrow_forwardA compound has the molecular formula CH40, and shows a strong IR absorption at 2850-3150 cm.
