how many grams are in 5.12 moles of Al
Answer:
138.14547456
Explanation:
How many moles Aluminium in 1 grams? The answer is 0.037062379468509.
We assume you are converting between moles Aluminium and gram.
You can view more details on each measurement unit:
molecular weight of Aluminium or grams
The molecular formula for Aluminium is Al.
The SI base unit for amount of substance is the mole.
1 mole is equal to 1 moles Aluminium, or 26.981538 grams.
Note that rounding errors may occur, so always check the results.
Use this page to learn how to convert between moles Aluminium and gram.
Answer:
[tex]\boxed {\boxed {\sf About \ 138 \ grams \ of \ aluminum}}[/tex]
Explanation:
To convert from moles to grams, we must use molar mass.
This can be found on the Periodic Table, so look for the symbol for aluminum: Al
Al: 26.981538 g/molWe can use this number as a ratio.
[tex]\frac { 26.981538 \ g \ Al} { 1 \ mol \ Al}[/tex]
Multiply by the given number of moles: 5.12
[tex]5.12 \ mol \ Al *\frac { 26.981538 \ g \ Al} { 1 \ mol \ Al}[/tex]
Multiply. The moles of aluminum will cancel.
[tex]5.12*\frac { 26.981538 \ g \ Al} { 1}[/tex]
[tex]138.145475 \ g \ Al[/tex]
Round. The original measurement of moles has 3 significant figures, so our answer must also have 3 sig figs.
For the number we calculated, that is the ones place. The 1 in the tenth place tells us to leave the 8.
[tex]138 \ g \ Al[/tex]
There is about 138 grams of aluminum in 5.12 moles.

Write a paragraph that explains diffusion and osmosis and how it relates to the circulatory system. Each sentence should be typed in the appropriate color.
It should include an introductory sentence that restates the question. A sentence that explains diffusion. A sentence that explains osmosis and at least 2-3 sentences that explain the relationship between diffusion, osmosis and the circulatory system. And, lastly, a conclusion sentence.
Materials are transferred between individual cells and their internal environment through the cell membrane by diffusion, osmosis, and active transport. During diffusion and osmosis, molecules move from a higher concentration to a lower concentration. Osmosis: Osmosis is the movement of solvent particles across a semipermeable membrane from a dilute solution into a concentrated solution. Diffusion: Diffusion is the movement of particles from an area of higher concentration to lower concentration. This would be the diffusion.

Convert 4.56 g/ml to lb-fl-oz
Answer:
g-lb 0.01005308
ml-fl Oz 0.1541919
The value of 4.56 g/mL is 0.296 lb/fl-oz.
Explanation:
Given:
The density with 4.56 g/mL
To find:
Convert 4.56 g/ml to lb/fl-oz
Solution:
In 1 pound there are 453.592 grams:
[tex]1 pound = 453.592 grams\\1 grams=\frac{1}{453.592 } pounds\\4.56 g/mL=4.56\times\frac{1}{ 453.592} lb/mL\\=0.0100 lb/mL[/tex]
In 1 fluid ounce there are 29.5735 milliliters:
[tex]1 \text{fluid ounce} = 29.5735 milliliter\\1 mL=\frac{1}{29.5735} fl-oz\\0.0100 lb/mL=\frac{0.0100}{\frac{1}{29.5735}} lb/fl-oz\\0.0100 lb/mL=0.0100 \times\frac{29.5735}{1} lb/fl-oz\\=0.296 lb/fl-oz[/tex]
The value of 4.56 g/mL is 0.296 lb/fl-oz.

How many moles are present in 63.80L of oxygen gas, O2?
Answer:
2.85moles of oxygen gas
Explanation:
Given parameters:
Volume of oxygen gas = 63.8L
Unknown:
Number of moles = ?
Solution:
We assume that the gas is under standard temperature and pressure. To find the number of moles, use the expression below:
1 mole of a gas at STP occupies a volume of 22.4L
So;
63.8L of oxygen gas will take up a volume of
[tex]\frac{63.8}{22.4}[/tex] = 2.85moles of oxygen gas
