Answer: m = 0.448 g C9H8O4
Explanation: Solution attached
Convert molecules of C9H8O4 to moles using the Avogadro's number
Convert moles of C9H8O4 to mass using its molar mass.
This is a unit conversion problem. Nm (nanometer) is smaller than mm (millimeter).
1 mm = 1/10³m = 1 x 10⁻³ m
1 nm = 1/10⁹ m = 1 x10⁻⁹ m
1 m = 1 x 10⁹ nm
Hence, 2 mm = 2 x 10⁻³ m
Then we can convert 2 x 10⁻³ m to nm by multiplying with 10⁹.
Then 2 mm = 2 x 10⁻³ m = 2 x 10⁻³ x 10⁹ nm = 2 x 10⁶ nm.
Hence, the thickness of nickel is 2 x 10⁶ nm.

Ribosomes are essential cell components that facilitate protein synthesis by translating mRNA into proteins. These proteins play various important roles in cell and organism function and survival, making ribosomes key for growth and survival.
Ribosomes are essential organs within a cell that play a significant role in the protein synthesis process. They are primarily responsible for decoding an organism's DNA into RNA, specifically an mRNA (messenger RNA), which is then used as a template for constructing proteins, a process known as translation.
Proteins produced in ribosomes function in numerous ways, including as enzymes, antibodies, and cell membrane components. Without ribosomes cell would have no way of making these essential proteins.
This is why cells need ribosomes. They are indispensable for the growth and survival of cells and organisms, as they make proteins that are crucial for cell function and growth.

According to the forces of attraction, in the process of sublimation the substance changes from solid to gaseous form directly.
Forces of attraction is a force by which atoms in a molecule combine. it is basically an attractive force in nature. It can act between an ion and an atom as well.It varies for different states of matter that is solids, liquids and gases.
The forces of attraction are maximum in solids as the molecules present in solid are tightly held while it is minimum in gases as the molecules are far apart . The forces of attraction in liquids is intermediate of solids and gases.
The physical properties such as melting point, boiling point, density are all dependent on forces of attraction which exists in the substances.
