Answer:

6 atoms of carbon.

Explanation:

Hello,

In this case, we can easily compute how many times the molar mass of the empirical formula is in the molecular formula by firstly computing it:

[tex]M=12.01g/mol*1+1.01g/mol*1+35.45g/mol*2\\\\M=47.58g/mol[/tex]

Then, we divide them:

[tex]\frac{290.8g/mol}{47.58g/mol}= 6.111[/tex]

Which is approximately 6, for that reason, we are going to find six atoms of carbon in the molecule.

Regards.
