## anonymous one year ago An element has a mass of 9.1229*10^-23 g. Identify the element. I'm not sure where to begin to identify this element.

Hm, the question is a bit unclear, but I would guess that 9.1229*10^-23g is the mass of one atom? in that case, multiply the mass of the atom by Avogadro's number (6.022*10^23) to find the mass of one MOLE of that element. Then, look at the periodic table to find which element matches with the element you have here.

@Vocaloid Yes, it is very unclear that's why I'm so confused. Yes, it is the mass of one of the element's atoms. So, I take $\left( 9.1229*10^{-23} \right)*(\frac{ 6.022*10^23 }{ 1atm })$ and get the mass of one element to compare to the periodic table?

3. Vocaloid

yup! once you multiply those two numbers you will get the mass of one mole

4. Vocaloid

so what do you get when you multiply (9.1229*10^-23)*(6.022*10^23)?

Thank you! I got 54.9381038

6. Vocaloid

Yup, so which element is it?

7. anonymous

Manganese.
