What is the molar mass of sodium bicarbonate, in g/mol? Your answer should have the appropriate number of significant figures (u
Dmitry_Shevchenko [17]

Answer: 105.96

Explanation:

Sodium bicarbonate (Na2CO3)

Atomic mass of Sodium (Na) = 22.99

Atomic mass of Carbon (C) = 12.01

Atomic mass of oxygen = 15.99

Na2CO3 has a molar mass of (22.99x2) + 12.01 + (15.99x3) which is equal to

45.98 + 12.01 + 47.97 = 105.96

Thus, the molar mass of sodium bicarbonate is 105.96g/mol

The diagram shows two cells. Identify structures C, D, and E and explain how they work together to perform a specific process wi
soldi70 [24.7K]

Structure C, D, and E in the diagram represent the endoplasmic reticulum, the ribosome, and the Golgi apparatus respectively.

When the ribosomes are attached to the endoplasmic reticulum, they give it a rough appearance.

The ribosome, endoplasmic reticulum, and the Golgi apparatus work together in the synthesis and transport of protein within the cell. In other words, they are all involved in the secretory pathway of cells.

  • The ribosome represents the actual site of protein synthesis.
  • The endoplasmic reticulum gets involved by folding the synthesized proteins and packaging them into secretory vesicles. Thereafter, the vesicles are transported to the Golgi apparatus.
  • The packaged proteins undergo further processing within the Golgi apparatus before they are exported to the cell membrane via the cytosol.

In other words, the 3 organelles work together to form the secretory pathway of the cell. They are involved in the synthesis, packaging, processing, and eventual transport of proteins to their target sites.

2 decided by 5/12 in fraction
Rudiy27

Answer:

\frac{24}{5}

Explanation:

\frac{2}{1} ÷ \frac{5}{12} =

To change the ÷ sign to a × sign, swap the denominators and the numerators of the second fraction.

\frac{2}{1} × \frac{12}{5} = \frac{24}{5}

Directly multiply. Numerators with numerators and denominators with denominators.
