Question

qual valor de atomos contem em 49g de H2SO4

Answer 1

$Ol\acute{a}~~\mathbb{MAT} \\ \\ Massa~molar~de~H_2S0_4=\underbrace{1.2+32+16.4}_{98} \\ \\ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~=\boxed{98g/mol } \\ \\ 1mol----\ \textgreater \ 98g------\ \textgreater \ 6,022.10 ^{23} ~\hat{a}tomos \\ ~~~~~~~~~~~~~~~~~~~~~~~~49g------\ \textgreater \ x \\ \\~~~~~~~~~~~~~~~~~~~~~~~~ x= \frac{49.(6,022.10 ^{23} }{98} \hat{a}tomos \\ \\ ~~~~~~~~~~~~~~~~~~~~~~~~x=\boxed{\boxed{3,011.10 ^{23} \hat{a}tomos}}$
