Solved How many atoms are there in 39.6 g of tin (Sn)?
WebJun 15, 2024 · Explanation: We got a molar quantity of 39.1 ⋅ g 180.16 ⋅ g ⋅ mol−1 = 0.217 ⋅ mol ... Now clearly, there are 24 atoms per molecule of glucose...and 6.022 × 1023 ⋅ atoms⋅ mol−1 ... And so we take the product.... 6.022 × 1023 ⋅ mol−1 ×0.217 ⋅ mol ×24 = 3.14 ×1024 ⋅ atoms.
