How many molecules of hydrogen dioxide are in 8.54 moles of hydrogen dioxide? i think that is what h and o are, but it wasn't letting me type them together. answer really quick

We have 5.14 * 10^24 in 8.54 moles of hydrogen dioxide

Explanation:

Step 1: Data given

Moles of hydrogen dioxide = 8.54 moles

Number of avogadro = 6.022 * 10^23

Step 2: Calculate molecules

Number of molecules = number of moles * Number of avogadro

Number of molecules = 8.54 moles * 6.022 *10^23

Number of molecules = 5.14 * 10^24

We have 5.14 * 10^24 in 8.54 moles of hydrogen dioxide

a electronegativity decreases beacuse the size of nucleus is bigger.
