Question

Which of the following is Loschmidt number? (A) 6 × 1023 (B) 3 × 1023 (C) 2.69 × 1019 (D) None of these

Tardigrade Admin · Accepted Answer

The no. of molecules present in 1 mL of gas at STP is known as Loschmidt number. 22400 ml of gas has total no. of molecules =6.023 × 1023 1 ml of gas has total no. of molecules =(6.023 × 1023/22400) =2.69 × 1019

Q. Which of the following is Loschmidt number?

$6 \times 1 0^{23}$

$3 \times 1 0^{23}$

$2.69 \times 1 0^{19}$

None of these

The no. of molecules present in $1 m L$ of gas at $STP$ is known as Loschmidt number.

$22400 m l$ of gas has total no. of molecules $= 6.023 \times 1 0^{23}$

$1 m l$ of gas has total no. of molecules $= \frac{6.023 \times 1 0 ^{23}}{22400}$

$= 2.69 \times 1 0^{19}$
