The explosive reactions may be triggered by spark, heat, or sunlight. A mole of C-12 by definition weighs exactly 12 g and Avogadro's number is determined by counting the number of atoms. A. Suppose that you wantto know how many hydrogen atoms are in a mole of water molecules. {border-color:#8f8f8f;}ul.footer_links a:hover .ec_product_li, li.ec_product_li{ width:50%; } " Brings you back to basics! .ec_category_li:nth-child( 2n+1 ) .ec_product_editor{ left:227px; } .ec_details_mobile_title_area{ display:block; } The one and only electron ring around the nucleus of each hydrogen atom has only one electron. There are 4 Hydrogen atoms in one molecule of methane, or 2 We have 2H2 + O2 in 1 mole you have 6.022*10^23 molecules. The mass of 1.75 mol of S2Cl2 is calculated as follows: \( moles\; S{_{2}}Cl_{2} \left [molar\; mass \dfrac{g}{mol} \right ]= mass\; S{_{2}}Cl_{2} \), \( 1.75\; mol\; S{_{2}}Cl_{2}\left ( \dfrac{135.036\; g\; S{_{2}}Cl_{2}}{1\;mol\;S{_{2}}Cl_{2}} \right )=236\;g\; S{_{2}}Cl_{2} \).
