Answer:
One mole of substance contains 6.023×1023 particles.
In CO2, Molecular mass =44g=1mole
Given : 3.0115×1023 particles present in CO2
∴ Number of moles in 3,0115×1023 particles of CO2,
=6.023×10233.0115×1023=0.5

the answer is 200 g
step-by-step explanation
moles of x = (3.0115 * 10^19)÷
(6.023 * 10^23)
= 1 by 2 * 10^-4
now
=>1 by 2 * 10^-4mole = 1 * 10^-2g
=> 1 mole = 2 * 10^ -2 * 10^4
= 200g
