What is the mass in milligrams of 4.30 moles of sodium?use âeâ for âÃ10" and use significant figures?

Elis [28]

First, calculate the mass of sodium in g with the help of molar mass and number of moles.

Number of moles = $\frac{given mass in g}{molar mass}$ (1)

Molar mass of sodium = $23 .0 g/mol$

Substitute the given value of number of moles and molar mass of sodium in formula (1)

$4.30 moles = \frac{given mass in g}{23.0 g/mol}$ (1)

$4.30 moles\times 23.0 g/mol = mass in g$ (1)

mass of sodium in g = $98.9 g$

Now, according to conversion factor, 1 g = 1000 mg

So, $98.9 g$ of sodium = $98.9 \times 1000 mg$

= $98900 mg$ of sodium

Thus, mass of sodium in mg = $9.89 \times 10^{4} mg$

The majority of water molecules moving across plasma membranes by osmosis do so via a process that is most similar to ____.

ValentinkaMS [17]

Answer:

The answer is Facilitated Diffusion

Explanation:

Osmosis is most similar to facilitated diffusion.

Osmosis can be defined as : Osmosis is the movement of water molecules across a semi-permeable membrane, down a concentration gradient from a low concentrated solution into a more concentrated solution.

Facilitated diffusion is defined as: Facilitated diffusion is the flow of molecules requiring the aid of a protein, across a membrane, down a concentration gradient from a low concentrated solution into a more concentrated one.

Anit [1.1K]

Answer: The percent yield of the reaction is 32.34 %

Explanation:

To calculate the number of moles, we use the equation:
