If one mole of carbon atoms weighs 12 grams what is the mass in grams of one atom of carbonAnwers in full of explanation |
|
Answer» Answer: We have GIVEN that one mole of carbon atom weighs 12 g. A mole is defined as exactly equal to 6.022×1023 atoms. So, we know that a mole of carbon contains 6.022×1023 atoms. Therefore, we can write the mass of 6.022×1023 atoms = 12 g. Using the unitary method to find the mass of 1 atom of carbon in grams. So, we can write as below- So, now mass of 1 atom of carbon will be =126.022×1023=1.993×10−23g Hence, the mass in grams of 1 atom of carbon is 1.993×10−23g . If we have to find the mass of 2 atoms or n number of carbon atoms, the same way we can PROCEED to find the mass in grams of the carbon atoms. Note – While solving the QUESTION, the first thing we should know is about mole. A mole is defined exactly equal to 6.022×1023 of some chemical unit, whether it be atoms, MOLECULES, ions, or others. So, as mentioned in the solution, the mass of 1 mole is given, so we can easily find the mass of 1 atom of carbon. Explanation: mark me brailiest |
