Five moles of sulfur dioxide, soz, would consist of how many molecules?<br> molecules<br> Need Help?
Amiraneli [1.4K]

Answer:

3 x 10²⁴ molecules

Explanation:

A mole is just a name that we use to substitute a number, just like a dozen means 12, a mole means 6.022 x 10²³. This gives us the unit conversion of 6.022 x 10²³ molecules SO₂/1 mol SO₂.

5molSO2*\frac{6.022 x 10^2^3molecules}{1mol SO2} = 3.011 x 10^2^4moleculesSO2

Round to the lowest number of significant figures to get 3 x 10²⁴ molecules SO₂

How many magnesium ions are present in 5.36 x 10-4 mol of magnesium iodide?
WARRIOR [948]
Magnesium iodide = MgI₂
mass of Mg = 24.3g
mass of I = 126.9g
mass of MgI₂ = 24.3 + 2*126.9 = 278.1g = 1 mole

in 5.36x10⁻⁴ mole of MgI₂ ---------------- x g of Mg
in 1 mole of MgI₂ ------------------------------ 1 mole of Mg
x = 5.36x10⁻⁴ moles of Mg = 0.000536 moles of Mg

answer: we've 0.000536 moles of Mg (magnesium ions) in 5.36x10⁻⁴ moles of MgI₂
