Question

Calculate the mass of 1.050 5 into 10 to the power 23 molecules of carbon dioxide

Answer 1

Answer : The mass of carbon dioxide is, 7.675 grams

Solution:-

1 mole weighs 44 gram of carbon dioxide which contains 6.022×10^23 number of molecules

As,6.022×10^23 number of molecules present in 44 grams of carbon dioxide molecule

So,1.0505×10^23 number of molecules present in1.0505×10^23/6.022×10^23 × 44 =7.675 grams of carbon dioxide molecule

Therefore, the mass of carbon dioxide is, 7.675 grams
