How many moles of Nickel reacts with 9.81 moles of HCl?
1Ni + 2HCl --> 1NiCl + 1H2
I know how to find the molar masses of each. I have also converted the 9.81 moles of HCl to grams, which is 357.67g. I am really confused about how to determine the moles of Nickel that react with 9.81 moles of HCl. So, if anyone could help me I WOULD GREATLY APPRECIATE IT!! SHOW ALL WORK PLZ! N THANKS
