How many moles of silicon (si) atoms are equivalent to 65.8g si? a) 0.427 g b) 2.34 mol c) 4.70 g d) 1,850 mol explain this because i'm hopeless and

using the periodic table find the molar mass of silicon

(28.0855)

 then divide the grams by that:

65.8 / 28.0855 = 2.34

Answer is B.

I explained it like you asked.

if you mean hydrogen and oxygen then water is the product
