The volume measured using such a cylinder will be reported to the nearest 10th mL.
<h3>Cylinder graduation</h3>
10 mL graduated cylinders are always read to the nearest two decimal places.
100 mL graduated cylinders are always read to the nearest 1 decimal place. The nearest 1 decimal place is the same thing as the nearest 10th.
Thus, a reading made using a 100mL increment graduated cylinder would be reported to the nearest 10th mL.

<u>Answer:</u> Boyle's law states that gas volume is inversely proportional to pressure.
<u>Explanation:</u>
Boyle's law is one of the law used to determine the Ideal Gas equation.
This law states that pressure of the gas is inversely proportional to the volume of the gas at constant temperature and number of moles
Mathematically,
(at constant temperature and number of moles)
The above expression can also be written as:
where,
are initial pressure and volume of the gas
are final pressure and volume of the gas
Hence, Boyle's law states that gas volume is inversely proportional to pressure.
Answer:
Primary structure is the correct answer.
Explanation:
- The primary structure is the simple level of protein structure.
- Primary structure is a basic amino acids sequences in a protein.
- In the primary structure, amino acids are attached together by a covalent bond.
- Primary structure is when the amino acids are joined together with peptide bonds to produce polypeptide chains
- Changes in pH are least likely to change the amino acid sequence or disrupt peptide bonds.

Answer:
Hence, 15.99 g of solid Aluminum Sulfate should be added in 250 mL of Volumetric flask.
Explanation:
To make 0.187 M of Aluminum Sulfate solution in a 250 mL (0.250 L) Volumetric flask
The molar mass of Aluminum Sulfate = 342.15 g/mol
Using the molarity formula:-
Molarity = Number of moles/Volume of solution in a liter
Number of moles = Given weight/ molar mass
Molarity = (Given weight/ molar mass)/Volume of solution in liter
0.187 M = (Given weight/342.15 g/mol)/0.250 L
Given weight = 15.99 g
Answer:
3.51× 10²³ formula units
Explanation:
Given data:
Mass of CaO = 32.7 g
Number of formula units = ?
Solution:
First of all we will calculate the number of moles.
Number of moles = mass/molar mass
Number of moles = 32.7 g/ 56.1 g/mol
Number of moles = 0.583 mol
Number of formula units:
1 mole = 6.022 × 10²³ formula units
0.583 mol × 6.022 × 10²³ formula units / 1 mol
3.51× 10²³ formula units
The number 6.022 × 10²³ is called Avogadro number.
