A sample of hydrogen nitrate or nitric acid, HNO 3 contains 18.8 x 1022 molecules.
IgorC [24]

Answer:

19.7 g.

Explanation:

Hello there!

In this case, according to the given information, it turns out possible for us to realize this problem can be solved by using a molecules-moles-mass relationship, starting with the given molecules, using the Avogadro's number and the molar mass of nitric acid (63.01 g/mol):

18.8x10^{22}molec*\frac{1mol}{6.022x10^{23}molec}* \frac{63.01g}{1mol} \\\\=19.7g

Regards!
