Question

N=0,3×10^23 M=142г/моль m=?

Answer 1

Ν - "ню" 
ν = N / N a, где N a - число "Авогадро" (постоянная величина) 
m = v * M, где M - молярный объем озона 

ν (O3) = 3*10^23 молекул / 6,02*10^23 моль = 0,5 моль 
m (O3) = 0,5 моль*48 г/моль = 24 г 
Ответ: 24 г

Answer 2

To find the mass (m) in grams, we can use the formula:

$m = \frac{N}{N_A} \times M$

Where:

• $N$ is the number of atoms or molecules (in this case $3 \times 10^{23}$)
• $N_A$ is Avogadro's number ($6.02214076 \times 10^{23}$ mol$^{-1}$)
• $M$ is the molar mass in grams per mole (in this case 142 g/mol)

Substituting the given values:

$m = \frac{3 \times 10^{23}}{6.02214076 \times 10^{23}} \times 142$

$m \approx 235.4 \text{ grams}$

So, with $N = 3 \times 10^{23}$, $M = 142 \text{ g/mol}$, the mass ($m$) is approximately 235.4 grams.
