Answer:

- Nucleus Function - Controls and regulates the activity of the cell.

- Ribosome builds proteins.

- A vesicle structure is kinda like a sac filled with a fluid of sorts.

- Rough ER has ribosomes attached to the cytoplasmic side of the membrane.

- Golgi apparatus kinda looks like a "stack of peta bread"

- Golgi apparatus functions as a factory in which proteins received from the ER are further processed and sorted for transport to their eventual destinations

The cytoskeleton of a cell is made up of microtubules, actin filaments, and intermediate filaments.

- The smooth endoplasmic reticulum functions in many metabolic processes. It synthesizes lipids, phospholipids as in plasma membranes, and steroids.

- The mitochondria produced energy/ATP

- Mitochondria have a double membrane arrangement that separates the organelle into four distinct compartments

- The cytosol contains an organized framework of fibrous molecules that constitute the cytoskeleton

A concentrated salt solution has a mass of 5.29 g for a 5.00 mL sample. What is the specific gravity of this solution
TiliK225 [7]

Answer:

\rho_s=1.07g/cc^3

Explanation:

From the question we are told that:

Mass M=5.29g

Volume V=5.00mL=>5.0cc^3

Generally the equation for Specific Gravity momentum is mathematically given by

Specific\ Gravity\ g= Density\ of\ Salt\ Solution\ \rho_s / Density\ of\ Water\ \rho_w

 g=\frac{ \rho_s} { \rho_w}

 \rho_s=\frac{ g} { \rho_w}

 \rho_s=\frac{ 5.29} { 5}

 \rho_s=1.07g/cc^3

How many atoms are in 18.016g of Sulfur?
Stella [2.4K]
That means that one mole of sulfur has a mass of 32.065 grams. b) This compound contains two hydrogen atoms and one oxygen atom. To find the molar mass of H2O, we need to add the mass of two hydrogen atoms plus the mass of one oxygen atom. We get: 2(1.008)+16.00=18.016g/mol.
