hello,
to find the no. of molecules we have to find moles in molecule of 16g of oxygen and molecule of 2g of carbon
no. of moles(n)=given mass(w)/molecular weight(m)
1 molecule of oxygen is O₂ has mass of 16+16=32u
n=16/32
n=1/2 moles
now,n=no. of particles(N)/avogradro no.(N₀)
1/2=(N)/6.022×10²³
n=3.011×10²³ atoms
1 molecule of carbon is C has mass 12u
n=2/12
n=1/6 moles
n=N/N₀
n=N/6.022×10²³
n=1.003×10²³ atoms
hope this helps,if u like it please mark it as brainliest

Thank you !
ur welcome do u have any other questions
i am free
Okay!!
what are ur questions?
WAIT?
In each paper clip represent particles how many particles are there in 12 of carbon? in 16g of OXYGEN? In 7g of LITHIUM ? In 14g of NITROGEN? in 29g Of SILICOn??
In each paper clip represent 1x10^^23 particles how many particles are there in 12 of carbon? in 16g of OXYGEN? In 7g of LITHIUM ? In 14g of NITROGEN? in 29g Of SILICOn??
ok i will solve them
Thank you
