Answer:
1 = 1.203 L.
2 = 1.291 dg.
3 = 843.062 - 638.1848 = 204.8772
The answer consist of seven significant figures.
4= 123.0 × 8.43 = 1036.89
answer consist of six significant figures.
Explanation:
Q 1 = part 1
Convert the 1202.57120 mL into L
Both milliliter and litters are the unit of volume. Liter is larger unit while milliliter is the smaller unit. One liter is equal to the thousand milliliter. In order to convert the milliliter into liter we will divide the given value by thousand.
1202.57120 / 1000 = 1.2025712 L
By rounding the answer into four significant figures 1.203 L.
Q 1 = Part 2
Convert the 0.1290743 g into dg.
The gram and decigram are both the unit of mass. gram is larger unit decigram is smaller unit. one gram is equal to 10 dg. In order to convert the gram unto dg we will multiply the value with 10.
0.1290743 × 10 = 1.290743 dg
By rounding the answer into four significant figures 1.291 dg.
Q 1 = part 3
843.062 - 638.1848 = 204.8772
The answer consist of seven significant figures. The zero between the 2 and 4 is also a significant. If we have to round the answer in four significant figures the answer will be 204. 9.
Q 1 = part 4
123.0 × 8.43 = 1036.89
answer consist of six significant figures. if we round the answer into four significant figures then answer will be 1037.
A graduated cylinder must be tipped over to add small amounts, and it would be very difficult to control the amount that is dropped into the analyte. On the other hand, a buret has a stopcock that can be controlled much more easily, by simply turning or pressing on it (depending on the type of buret). This allows a more controlled release, which is essential because one slows down the rate of dropping the titrant when close to the end point of titration.
