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

Monosodium glutamate (NaC5H8NO4) is used extensively as a flavor enhancer what is its percent composition
tensa zangetsu [6.8K]

Answer:

% sodium= 13.6 % sodium

% carbon= 35.5 % carbon

% hydrogen= 4.7% hydrogen

% nitrogen = 8.3% nitrogen

% oxygen = 37.8 % oxygen

Explanation:

To find its percent composition means that we are to find to find the percentage of each of the constituents of the compound present.

The molar mass of monosodium glutamate is 169.11 gmol-1

Hence;

Percent of sodium= 23 gmol-1/169.11 gmol-1 × 100 = 13.6 % sodium

Percent of Carbon= 60 gmol-1/169.11 gmol-1 ×100 = 35.5 % carbon

Percent of hydrogen= 8/169.11 gmol-1 ×100 = 4.7% hydrogen

Percent nitrogen = 14/169.11 gmol-1 × 100 = 8.3% nitrogen

Percent oxygen = 64/169.11 gmol-1 ×100 = 37.8 % oxygen

Si se tiene 1mol de NO . cuantas moleculas de NO hay
kumpel [21]

if you have 1mol of NO. how many molecules of NO are there

Answer:

6.02 x 10²³ molecules

Explanation:

Given parameters:

Number of moles of NO = 1 mole

Unknown:

Number of molecules in NO;

Solution:

A mole of compound contains the Avogadro's number of particles.

  1 mole of a substance contains 6.02 x 10²³ molecules

So, 1 mole of NO contained 6.02 x 10²³ molecules
