A 4.99 g sample of an unknown element contains 1.07 × 1023 atoms. Identify the unknown element.
Question
Solution 1
To identify the unknown element, we need to find its atomic mass. We can do this by using Avogadro's number, which states that one mole of any substance contains 6.022 x 10^23 entities (atoms, in this case).
Step 1: Calculate the number of moles in the sample We know that the sample contains 1.07 x Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
