HI. How many ATOMS of sulfur are present in 4.25 moles of sulfur tetrafluoride ?

\(SF_4 \ sulfur \ tetrafluoride\)

\(SF_4 \ molar \ mass=108,057g/mol\)

\(S \ atom \ mass=32,065\ g/mol\)

\(F \ atom \ mass=18,998\ g/mol\)

\(One \ mole \ of \ a \ substance \ contains \ about \ 6.022 \times10^{23} \ particles.\)

\(\frac{4mol F}{molSF_4}\times4.25\ mol\times 6.022\times10^{23}/mol=1.02374\times 10^{25}\)

1.02374 • 10²⁵ ATOMS of sulfur are present

in 4.25 moles of sulfur tetrafluoride .
