Web30 dec. 2024 · How many moles are in 12 grams of helium? 1 mole is equal to 1 moles Helium, or 4.002602 grams. How many atoms of helium are present in 20g of helium? 1 mole of He contains 6.023×10^23 atoms. 1 mole of He = 4 gm of He. So, 20 gm of He contains — (20÷4)×6.023×10^23 atoms = 3.011×10^24 He atoms. WebThe conversion factor needed to convert between grams and moles is the molar mass. First we need to calculate the molar mass of CH 4, following the procedure in Example 3.5: molar mass of CH 4 = 12.01 g + 4(1.008 g) = 16.04 g Because 1 mol CH 4 = 16.04 g CH 4 the conversion factor we need should have grams in the
