A sample of 0.300 mol of a metal m reacts completely with excess fluorine to form 23.4 g of mf2. what element is represented by
Phoenix [80]

Molecular weight of m is 40g. Hence, name of element m is Calcium. which is represented by the symbol Ca.

Given,

Moles of metal M = 0.300 moles

 weight of mF₂ formed =23.4g

we have to find the name of element m...

Now,

 m + F₂ → mF₂

1 mole of m reacts with 1 mole of F₂ (or 2 molecule of flourine) to form 1 mole of mF₂

Hence,

 0.300 moles of m reacts with 0.300 moles of F₂ to form 0.300 moles of mF₂.

 

Hence,

 23.4 g = 0.300 moles of mf2

0.300 × 38g + 0.300 × m = 23.4 g

Hence

 m = 40 g

So, molecular weight of m is 40g. Hence, name of element m is Calcium. which is represented by the symbol Ca.

 Thus, from the above conclusion we can say that, name of element m is Calcium. which is represented by the symbol Ca.

Calculate the percentage by mass of oxygen in Al2(SO4)3 (Al=27, S=32,O= 16) PLEASE SHOW FULL WORKING​
White raven [17]

Answer:

There is 61.538% oxygen in Al2(SO4)3.

Explanation:

Wt Of oxygen in the compound = 12*16 = 192 amu.

Total Wt. Of the compound = 2*12+3*32+12*16 = 312 amu.

Thus, percent of oxygen = Wt of oxygen/total Wt. Of compound *100

= 192/312 * 100=61.538 %

Sodium hydroxide is extremely soluble in water. At a certain temperature, a saturated solution contains 527 g NaOH(s) per liter
Alona [7]

<u>Answer:</u> The molarity of solution is 13.175 M.

<u>Explanation:</u>

To calculate the molarity of solution, we use the equation:

\text{Molarity of the solution}=\frac{\text{Mass of solute}}{\text{Molar mass of solute}\times \text{Volume of solution (in L)}}

We are given:

Mass of solute (sodium hydroxide) = 527 g

Molar mass of sodium hydroxide = 40 g/mol

Volume of solution = 1 L

Putting values in above equation, we get:

\text{Molarity of solution}=\frac{527g}{40g/mol\times 1L}\\\\\text{Molarity of solution}=13.175M

Hence, the molarity of solution is 13.175 M.
