A compound is composed of 13% carbon, 4.3% hydrogen, 30.4% nitrogen, and 52.2% oxygen. The mystery compound has a molar mass of

vredina [299]

Answer:

C₂H₈N₄O₆ is the molecular formula for the compound

Explanation:

Data from the problem:

13 g of C in 100 g of compound

4.3 g of H in 100 g of compound

30.4 g of N in 100 g of compound

52.2 g of O in 100 g of compound

Firstly we determine, the mass of each in 184 g of compound, which is 1 mol

(13 g / 100 g) . 184 g = 24 g C

(4.3 g / 100 g) . 184 g = 7.91 g H ≅ 8 g H

(30.4 g / 100 g) . 184 g = 56 g N

(52.2 g / 100 g) . 184 g = 96 g O

And now, we divide the mass by the molar mass of each to determine the moles:

24 g C / 12 g/mol = 2 mol C

8g H / 1 g/mol = 8 mol H

56 g N / 14 g/mol = 4 mol N

96 g O / 16 g/mol = 6 mol O

So the molecular formula of the compound is C₂H₈N₄O₆

Lelechka [254]

gas to liquid

Explanation:

The change of state indicated by this analogy is from gas to liquid.

Cylinder to the left is filled with gases

Cylinder to the right is made up of liquid.

Gases occupy the volumes of containers they are introduced into.
They are random and possess a high kinetic energy.
Liquids have definite volume and flow with one another.
The gases in A are dispersed and in random motion.
This phase change is called condensation

How many atoms of hydrogen are in 0.56 mol of (NH4)2SO4

BabaBlast [244]

<h2>Answer: $2.7\times 10^{24}$ atoms</h2>

Explanation:

The given formula of the compound is $(NH_{4})_{2}SO{4}$

The formula says

Every mole of $(NH_{4})_{2}SO{4}$ contains $8$ moles of atoms of hydrogen.

Given that number of moles of compound is $0.56$

So,the number of moles of hydrogen atoms present is $0.56\times 8=4.48$

Since each mole has $6.022\times 10^{23}$ atoms,

$4.48$ moles has $4.48\times 6.022\times 10^{23}=2.7\times 10^{24}$ atoms.
