How many grams of SnO2 are required to produce 1.20x10^21 molecules of water?

Drupady [299]

Answer:

<u>0.150 grams</u>

<u></u>

Explanation:

The balanced chemical reaction to obtain water from SnO₂ is:

SnO₂ + 2H₂ → Sn + 2H₂O

The mole ratio is:

$\dfrac{1molSnO_2}{2molH_2O}$

Find the number of moles equivalent to 1.20× 10²¹ molecules of water, using Avogadro's number:

$1.20\times 10^{21}molecules\times \dfrac{1mol}{6.022\times 10^{23}molecules}=1.9927\times 10^{-3}moles$

From the mole ratio, the number of moles of SnO₂ are half the number of moles of water. That is:

0.0019927 moles / 2 = 0.00099635 moles of SnO₂

Use the molar mass of SnO₂ to convert the number of moles to grams:

molar mass of SnO₂ = 150.71g/mol

mass of SnO₂ = 0.00099635mol × 150.71 g/mol = 0.150 grams.

The answer must be reported with 3 significant figures.
