<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.

Number of nucleon =

Molarmassofnucleon

Massofatom

=

1.6726×10

−24

g/nucleon

3.32×10

−23

g

=19.8=20(approximately)

It is given that element comprises of 2 atoms

Hence,number of nucleon = 2×20=40

You have 4.70 mol H2O

There are two H atoms in 1 molecule H2O.

Therefore, there must be 2*4.70 = 9.40 mols H in 4.70 mols H2O.

How many mols O in 4.70 mols H2O? That's 4.70 mols, of course.

Said another way, you have 2 mols H for every 1 mol H2O and 1 mol O for every 1 mol H2O.

So for 50 mols H2O you have 100 mols H and 50 mol O.

When two plates with continental crust converge, why are neither of them subducted
Vikentia [17]

Neither plate subducts because the crust have approximately the same density. Instead, the rocks are smashed together causing them to recrystallize due to the intense heat and pressure from the colliding plates.
