Question

calculate the total number of atoms in 150g of carbon dioxide

pls answer this question pls​

Answer 1

32.80 g of Cu × 1 mol Cu / 63.55 g Cu = 0.52 mol of Cu

.....

Answer 2

First you need to find relative molecular mass. You can calculate it using relative atomic mass of C and O So

MCO2=12+16×2

=44gmol−1

molecular mass of CO2 is 44. Which mean 44 grams of CO2contain Avogadro’s number of atoms. So,

44gmol−1=6.022×1023mol−1(Avogadro’s number)

442=6.022×10232

22g=3.011×1023

So 22g of CO2have 3.011×1023 CO2molecules.

Since one molecule has one carbon atom it also has 3.011×1023 Carbon atoms

it is of 22kg like this you can 150g also
