Si Atomic mass=28.055amu Atomic number=14 Avagardo's... show more I'm struggling with these conversion factors it would be helpful if someone could walk me through this HW problem step by step in detail please and thanks a lot.(i keep getting it wrong) Here's some info on Silicon and a hint below.Si Atomic mass=28.055amu Atomic number=14 Avagardo's Number= 6.022x10^23 Hint given: First convert from atoms to moles using Avogadro\'s number, then from moles to grams using the molar mass of silicon.i keep getting it wrong) Here's some info on Silicon and a hint below.
