the molar mass is how many grams it takes to make a full mole.  The number  in carbon 12 tells us that it takes 12 g to makes a mole, so one half of that would be <u><em>option d, 0.5</em></u>.

Answer:

d. 0.5

Explanation:

A mole is the amount of matter that is present in a certain substance and it is compared or measured against the amount of particles that can be found in 12 grams of Carbon 12, which is the most common isotope of Carbon that can be found in nature, so if a substance has half of the particles as 12 grams of Carbon 12, that means that it is only half a mole, so there are .5 moles of the substance.

If a neutral atom has 24 electrons and 26 neutrons how many protons does it have?​
Salsk061 [2.6K]

Answer:

24

Explanation:

The number of protons in the atom of the neutral element will also be 24.

Protons are the positively charged particles in an atom.

Electrons are the negatively charged particles

Neutrons do not carry any charges at all

Now, in a neutral atom, the charge is balanced and the number of protons and electrons are the same in the atom.

So, since we have been given that the atom has 24 electrons, the number of protons will be 24.

If the compound has a molar mass of 156 g/mol, what is its molecular formula?
oksano4ka [1.4K]
I believe that the choices for this question are:
C2H4O2, C4H8O4 CH2O, C6H12O6 C3H6O3, C6H12O6 C2H4O2, C6H12O6 
 
The answer to this based on the molar masses given is:
C2H4O2, C6H12O6 
 
To prove calculate the molar mass:
C2H4O2 = 2*12 + 4*1 + 2*16 = 60
C6H12O6 = 6*12 + 12*1 + 6*16 = 180
