Find the percentage composition of a compound that contains 17.6 g of iron and
olganol [36]

Answer:

Explanation:

Your goal here is to figure out the mass of iron and the mass of sulfur present in exactly

100 g

of this compound, which is what you need in order to know the compound's percent composition.

The problem provides you with the mass of iron and with the mass of sulfur present in

27.9 g

of this compound, so you must use this information to scale up your sample from

27.9 g

to

100 g

.

To do that, set up the known composition of the compound as a conversion factor.

To find the number of grams of iron present in

100 g

of compound, set up the conversion factor like this

17.6 g iron

27.9 g compound

You will end up with

100

g compound

⋅

17.6 giron

27.9

g compound

=

63.1 g iron

To find the mass of sulfur present in

100 g

of compound, you can either use a conversion factor set up in a similar manner

100

g compound

⋅

10.3 g sulfur

27.9

g compound

=

36.9 g sulfur

or use the fact that the compound contains only iron and sulfur to say that the mass of sulfur will be equal to

100 g compound

−

63.1 g iron = 36.9 g sulfur

You now know the mass of iron and the mass of sulfur present for every

100 g

of compound, so you can say that the compound has the following percent composition

63.1% iron

36.9% sulfur

Here

%

means per

100 g

of compound.

Mass of oxygen gas needed to burn 37.5g of wax
Slav-nsk [51]
Answer is: mass oxygen is 129,28 grams.
Chemical reaction: 2C₁₈H₃₈ + 55O₂ → 36CO₂ + 38H₂O.
m(C₁₈H₃₈) = 37,5 g.
n(C₁₈H₃₈) = m(C₁₈H₃₈) ÷ M(C₁₈H₃₈).
n(C₁₈H₃₈) = 37,5 g ÷ 254 g/mol.
n(C₁₈H₃₈) = 0,147 mol.
From chemical reaction: n(C₁₈H₃₈) : n(O₂) = 2 : 55.
n(O₂) = 4,04 mol.
m(O₂) = 4,04 mol · 32 g/mol.
m(O₂) = 129,28 g.
