Question

how many molecules are in 0.0125 moles of sio2 ?​

Answer 1

Answer:

1.09 × N A , where   N A = Avogadro's Number

Of course, silicon dioxide is non-molecular, and I speak of formula units NOT molecules.

0.0 125 moles x 6.024 x $10^{23}$ molecules

= 0.0753 x $10^{23}$

Hope this helps you. Do mark me as brainliest.
