base

Explanation:

carbonic acid - H2CO3 - is a weak acid. Therefore, HCO3 itself is its conjugate base. The Na(sodium) ion is neutral.

This means that NaHCO3 is a base. (a weak one)

The answer is " $\bold{263 \ and \ 137.1 \frac{g}{ mol}}$ ".

Explanation:

The chemical formula for Salicylamide: C_7H_7NO_2

$\to (12.011 \ \frac{g}{mol} \times 7)+(1.008 \ \frac{g}{mol} \times 7)+(14.0067 \frac{g}{mol} \times 1)+(15.999 \frac{g}{mol} \times 2) \\\\\to (84.077 \ \frac{g}{mol} )+(7.056 \ \frac{g}{mol} )+(14.0067 \frac{g}{mol})+(31.998 \frac{g}{mol} ) \\\\\to (84.077 \ \frac{g}{mol} )+(7.056 \ \frac{g}{mol} )+(14.0067 \frac{g}{mol})+(31.998 \frac{g}{mol} ) \\\\ =137.1377 \approx 137.1\ \frac{g}{mol}$

The chemical formula of Iodosalicylamide: C_7H_6INO_2

$\to (12.011\frac{g}{mol}\times 7)+(1.008\frac{g}{mol}\times 6)+(126.904\frac{g}{mol}\times 1)+(14.0067\frac{g}{mol}\times 1)+(15.999\frac{g}{mol}\times 2) \\\\\to (84.077\frac{g}{mol})+(6.048\frac{g}{mol})+(126.904\frac{g}{mol})+(14.0067\frac{g}{mol})+(31.998\frac{g}{mol}) \\\\=263.0337 \approx 263.0\ \frac{g}{mol}$
