Mass of one atom
The given information states that the mass of one atom of element A is 3.9854×10^-23 g.

Mass in grams
To find the number of atoms in 1 g of element A, we need to convert the mass of one atom to grams. We can do this by multiplying the given mass of one atom by the conversion factor of 1 g/6.022×10^23 atoms (Avogadro's number).

Calculations
- Mass of one atom of element A = 3.9854×10^-23 g
- Conversion factor = 1 g/6.022×10^23 atoms

To convert the mass of one atom to grams, we can multiply the given mass of one atom by the conversion factor:
3.9854×10^-23 g * (1 g/6.022×10^23 atoms) = 0.0000000000000000000661 g

Therefore, the mass of one atom of element A is approximately 0.0000000000000000000661 g.

Number of atoms in 1 g
To find the number of atoms in 1 g of element A, we can divide the mass in grams by the mass of one atom:
1 g / 0.0000000000000000000661 g = 1.509×10^22 atoms

Therefore, there are approximately 1.509×10^22 atoms in 1 g of element A.

Conclusion
In conclusion, there are approximately 1.509×10^22 atoms in 1 g of element A. This calculation was done by converting the mass of one atom to grams and then dividing the mass in grams by the mass of one atom.
