♥️♥️​

Answer 1

$\huge\star\underline\mathscr\pink{HELLO}$

Atomic mass of oxygen = 16×2 = 32g/mol

32g of O2 = 1 mole

So, 12 g = $12 \times \frac{1}{32}$

= $\frac{6}{16}$

= $\frac{3}{8}$

= $0.375mole$

Answer 2

$n = \frac{w}{m}$

m=2*16=39

$according \: to \: the \: formula \\ \frac{w}{m} \\ = \frac{12}{32}$

=0.375moles
