Question

please help me with explanation ​

Answer 1

Answer:

4.15 × 10⁴⁷ atoms are present

Step-by-step explanation:

Here, molar mass of gas = 1.45 × 10^-24 gm

number of moles = mass/molar mass

= 1/(1.45×10^-24)

= 10²⁴/1.45

therefore,

total number of atoms = avogadro no × moles

= 6.022× 10²³ × (10²⁴/1.45)

= 4.15 × 10⁴⁷
