How many numbers of atoms there are in 1.14 mol of (SO3)
Pachacha [2.7K]

called the Avogadro number 

N(A)= 6.02 x 10^23 mol^-1 

1 mole of SO3 will contain 6.02 x 10^23 mol^-1 of SO3 molecules. 

thus, 1.14moles will contain; 

= 1.14mol x [3mol O/1mol SO3] x [6.02 x 10^23

atoms O/1mol O] 

= 2.05884 x 10^24 oxygen atoms 

= 1.14mol x [1mol S/1mol SO3] x [6.02 x 10^23

atoms O/1mol O] 

= 6.8628 x 10^23 sulfur atoms 

hope this helps:-)

WILL RATE BRAINLIST
svlad2 [7]

Answer:

The limiting reactant is the covers.

We are left with 3750 sheets of lined paper, 1125 sheets of graph paper and 25 staples.

Explanation:

the reaction is:

B - book

C - cover

Sl = sheet of lined paper

Sg - sheet of graph paper

St - staple

1B = 2C + 50Sl + 25Sg + 3St

We have covers for 150/2 = 75 books

We have lined paper for 7500/50 = 150 books

We have graph paper for 3000/25 = 120books

We have Staples for 250/3 = 83.(3) books, so for 83 books as we cannot make 1/3 of a book.

Because we only have covers for 75 books, covers are the limiting reactant.

After making 75 books we are left with:

0 covers

7500 - 75*50 = 3750 sheets of lined paper

3000 - 75*25 = 1125 sheets of graph paper

250 - 75*3 = 25 staples
