Answer:
Atomic mass of the element =Mass of one atom×6.02×10²³
=6.644×10-²³
×6.02×10²³
=40g
No. of gram atoms =
No.ofgram
Mass of the element in gram
= 40000/40
=1000 gram atoms
below answer is wrong by the way this is right.
mark me as brianliest.

Answer:
Mass of 1 mole Y atoms= mass of 1 atom × Avogadro constant
➾ 6.644 × 10-23 × 6.022×1023
➾ 40 g
♦ The atomic mass of Y = 40
= Mass of Y/Atmoic mass
= 40*1000/40
= 40
