How many atoms are in 9.008 mol of Carbon? 0.7500 atoms 1.332 atoms 5.423 x 10^24 atoms 1.496 x 10^ -23 atoms
Zanzabum

 The number  of atoms that are  in 9.008   moles of carbon is

5.423 x 10^24 atoms


<u><em>calculation</em></u>

The  number of atoms is calculated using the Avogadro's   constant

That is   According to  Avogadro's   1  moles  = 6.02 x 10^23  atoms

                                                         9.008  moles= ? atoms

by cross multiplication

= [(9.008  moles x 6.02 x 10^23 atoms)  / 1  mole] = 5.423 x10^24 atoms

What is the mole ratio of D to A in the generic chemical reaction? 4A + B --&gt; C + D​
storchak [24]
<h3>Answer:</h3>

Mole ratio of D to A is 1 : 4

<h3>Explanation:</h3>

We are given the generic chemical equation;

4A + B → C + D​

We are supposed to determine the mole ratio of D to A

What is mole ratio?

  • Mole ratio is the ratio of the number of moles of reactants or products in a chemical reaction.
  • We determine the mole ratio using the coefficients of reactants or products in question.

For example;

  • In the equation, 4A + B → C + D​, the coefficient of A is 4 while the coefficient of D is 1.
  • This means, 4 moles of A reacts with 1 mole of b to produce 1 mole of C and 1 mole of D
  • Thus, mole ratio of D to A  is 1 : 4

A particular brand of gasoline has a density of 0.737 g/ml at 25 ∘c. how many grams of this gasoline would fill a 13.0 gal tank
Usimov [2.4K]

Density of gasoline is 0.737 g/mL and volume of tank is 13.0 gal.

Since, 1 US gal=3.78 L

Volume of tank in L will be:

V=13.0 gal(\frac{3.78 L}{1 gal})=49.14 L

Also, 1 L=1000 mL

Thus,

V=49.14 L(\frac{1000 mL}{1 L})=49140 mL

Mass of gasoline can be calculated as follows:

m=d×V

Here, d is density and V is volume thus,

m=0.737 g/mL\times 49140 mL=3.62\times 10^{4}g

Therefore, mass of gasoline will be 3.62\times 10^{4}g.
