what type of apetite are you talking about
Try taking a better pic, it’s hard to read the questions.
Explanation:
solve fsolve for x in terms of r.
rx + 24 = -9or x in tsolve for x in terms of r.
rx + 24 = -9erms of r.
solve for x in terms of r.
rx + 24 = -9
rx + 24 = -9
Molar mass Na = 23 g/mol
23 g ------------- 6.02 x 10²³ atoms
4.56 x 10⁻² g ----- ? atoms
atoms = 4.56 x 10⁻² x ( 6.02 x 10²³ ) / 23
atoms = 2.74 x 10²² / 23
= 1.19 x 10²¹ atoms
hope this helps!
