Atomic number of carbon is 6 and hydrogen is 1, How many electrons are present In 1.6 grams of methane?

Explanation

To determine the number of electrons in 1.6 grams of methane (CH4), we first need to calculate the number of moles of methane present: Calculate the molar mass of methane: Molar mass of C = 12.01 g/mol Molar mass of H = 1.01 g/mol Molar mass of CH4 = (4 × 1.01 g/mol) +12.01 g/mol = 16.05 g/mol Calculate the number of moles of CH4: Moles of CH4 = mass of CH4 /molar mass of CH4 Moles of CH4= 1.6g / 16.05 = 0.0997 mol Calculate the number of electrons in 0.0997 mol of CH4: Each molecule of CH4 contains 10 electrons (4 from carbon and 1 from each of the four hydrogen atoms) Therefore, the number of electrons in 0.0997 mol of CH4 is: Number of electrons = 0.0997 mol × 6.02×10²³ molecules/mol × 10 electrons/molecule Number of electrons = 6.02 ×10²³electrons Therefore, there are approximately 6.02 × 10²³ electrons in 1.6 grams of methane.
