Question

500 milligram of co2

find the mole and molecule​

Answer 1

Answer:

no. of moles=2.2 X 10^-5;total no. of molecules=13.24 X 10^18

Explanation:

1mg=1/1000 g

given mass =0.001g

molar mass of carbon dioxide=44g

no. of moles = given mass/molar mass

= 0.001/44

=2.2 X 10^-5

total no. of molecules = no. of moles X Avogadro's no.

=2.2 X 10^-5 X 6.022 X 10^23

=13.24 X 10^18
