How many atoms does the sun have?

The atomic mass of hydrogen (the majority of the sun’s mass) is 1.00794 which means a mole — 6.022 × 10^23 atoms — of hydrogen weighs 1.00794 grams. So converting the sun’s weight to grams gives us 1.989 × 10^33 g. That means there are 1.973317 X 10^33 moles of hydrogen in the sun or ~1.1883315 × 10^57 atoms.
