Answer:

$\boxed {\boxed {\sf B. \ 3}}$

Explanation:

First, identify the elements.

H: Hydrogen
Cl: Chlorine
O: Oxygen

Next, identify any subscripts or coefficients. This would indicate there are multiple atoms of each element or group of elements.

There are none, so each element has 1 atom.

There are 3 elements with 1 atom each, so 3*1= 3

This chemical formula has <u>3 atoms</u> and B is correct.

PLEASE HELP ME<br><br> what would be the mass of 9.03 x 1021 molecules of hydrobromic acid (HBr)?

Nikitich [7]

We know 1 mole of any atom or molecules contains $6.033 \times 10^{23}$ atom or molecules.

1 mole of HBr i.e 81 gm/mol contains $6.033 \times 10^{23}$ atom or molecules.

So, mass of $9.03\times 10^{21}$ molecules is :

$m=\dfrac{81\times 9.03\times 10^{21} }{6.033 \times 10^{23}}\\\\m= 1.21\ gm$

Therefore, mass of $9.03\times 10^{21}$ molecules is 1.21 gm .

Hence, this is the required solution.
