How many O atoms are in 259 g of C12H210g? Molar mass of C12H210g = 309.29 g/mol 6.05 x 1024
4.54 x1024
5.40 x 1023
O 1.80 x 1024
106 x 1025

Ithink it’s 3 as the answer.

So3 that’s what i think

The main types of electromagnetic radiation. radio  waves have  the lowest frequencies  and  longest  wavelengths, while gamma  waves have highest frequencies  and shortest wavelengths. the wavelengths vary across the electromagnetic spectrum from about 10–15 m to more than 104 m.hope it !
