How many atoms are present in 354.22 g of cl2
Valentin [98]

Answer:

a) 3.0076 E24 atoms

Explanation:

  • mol ≡ 6.022 E23 atoms

∴ mass Cl2 = 354.22 g

∴ molar mass Cl2 = 70.906 g/mol

⇒ mol Cl2 = (354.22 g)*(mol/70.906 g) = 4.9956 mol

⇒ atoms Cl2 = (4.9956 mol)*(6.022 E23 atoms/mol)

⇒ atoms Cl2 = 3.008 E24 atoms

Ph4 is greater than ph6?.
Tatiana [17]

Answer:

Explanation: For example, pH 4 is ten times more acidic than pH 5 and 100 times (10 times 10) more acidic than pH 6. The same holds true for pH values above 7, each of which is ten times more alkaline (another way to say basic) than the next lower whole value.

A 48.3 mL sample of gas in a cylinder is warmed from 22 °C to
goldenfox [79]

Answer:

58.94 mL

Explanation:

V1 = 48.3 mL             V2 = v mL

T1 = 22 degree celsius OR 295 k         T2 = 87 degree celsius OR 360 k

We will use the gas equation:

PV = nRT

Since the Pressure (p) , number of moles (n) and the universal gas constant(R) are all constants in this given scenario,

we can say that

V / T = k , (where k is a constant)

Since this is the first case,

V1 / T1 = k --------------------(1)

For case 2:

Since we have the same constants, the equation will be the same

V / T = k (where k is the same constant from before)

V2 / T2 = k (Since this is the second case) ------------------(2)

From (1) and (2):

V1 / T1 = V2 / T2

Now, replacing the variables with the given values

48.3 / 295 = v / 360

v = 48.3*360 / 295

v = 58.94 mL

Therefore, the final volume of the gas is 58.94 mL
