**These flash cards require a Periodic Table and a calculator.****Using this equation:3H2 + N2 2NH3How many moles of H2**are needed to completely react with 2 moles of N2?**Using this equation:3H2 + N2 2NH3What would be the**mass (in grams) of 2 moles of N2?**How many moles of NH3 can be produced from 6 moles of N2?N2**+ 3H2 2NH3**If we need 631 g of sucrose, C12H22O11, how many moles would**that be?**If we need 3.0 moles of sand, SiO2 how many grams would we**need to measure out?**How many moles of H2 will completely react with 4 moles of**O2 ?2H2 + O2 2H2O
