To solve this question we have to find the moles of Aluminium. With the moles of Aluminium and the balanced reaction we can find the moles of Zn and its mass as follows:

<em>Moles Al -Molar mass: 26.98g/mol</em>

43.6g Al* (1mol/26.98g) = 1.616 moles Al

<em>Moles Zn:</em>

1.616 moles Al * (3mol Zn / 2mol Al) =

2.424 moles Zn are produced

<em>Mass Zn -Molar mass: 65.38g/mol-</em>

2.424 moles Zn * (65.38g / mol) =

<h3>158.5g Zn are produced</h3>

What is the mass in grams of a single atom of Pt?

Triss [41]

Answer:

3.23945533x $10^{-22}$ g

Explanation:

mass of 1 atom Pt = mass of a mole of atom Pt / 6.022 x $10^{23}$ = 195.08/6.022 x $10^{23}$ = 3.23945533x $10^{-22}$ g
