The mole is an SI unit representing a specific quantity of atoms of an element or molecules of a compound. There are 6.02 x 1023 atoms in a mole of an element or 6.02 x 1023 molecules in a compound. 6.02 x 1023 is known as Avogadro's number.

can you give me brainlyest? i need two more to level up

Answer:

247 grams NaCl

Explanation:

We want to convert 4.23 moles of NaCl into grams. To do so, we must first find the molar mass of NaCl.

According to the periodic table, it is 22.99 + 35.45 = 58.44 g/mol.

Now we must multiply the number of moles (4.23) by the molar mass to get the mass of NaCl:

4.23 mol * 58.44 g/mol ≈ 247 g

Thus, the answer is 247 grams of NaCl.

Answer:

Boil the water and stir in potassium nitrate. If it doesn't all dissolve, you can cook it on the stove or microwave it until the water boils again. Remove the solution from heat, but let it cool slowly for the best crystal formation.

How many gallons of gasoline that is 5% ethanol must be added to 2,000 gallons of gasoline with no ethanol to get a mixture that
Amanda [17]

Answer:

V_1= 3000 gal

Explanation:

We have 3 solutions:

  • Solution 1 (with ethanol)
  • Solution 2 (no ethanol)
  • Final solution

V_f=V_1 + V_2

and for the ethanol:

V_f*0.03=V_1*0.05 + V_2*0

V_f=V_1 \frac{5}{3}

Combining:

V_1 \frac{5}{3}=V_1 + V_2

V_1 \frac{2}{3}= V_2

V_1= \frac{3}{2} V_2

If V2=2000 gal:

V_1= \frac{3}{2} 2000 gal

V_1= 3000 gal

What is the ph of a buffer prepared by adding 0.607 mol of the weak acid ha to 0.609 mol of naa in 2.00 l of solution? the disso
Paraphin [41]

Given:

0.607 mol of the weak acid

0.609 naa

2.00 liters of solution

 

The solution for finding the ph of a buffer:

[HA] = 0.607 / 2.00 = 0.3035 M 
[A-]= 0.609/ 2.00 = 0.3045 M 
pKa = 6.25 

pH = 6.25 + log 0.3045/ 0.3035 = 6.25 is the ph buffer prepared.
