How many moles of carbon are in 3.7 moles of C 8 H11 NO2
Dafna1 [17]
In every molecule of C_{8} H_{11}NO_2 there is 8 atoms of Carbon.

IF we have 3.7 moles of C_{8} H_{11}NO_2 to find the number of moles of Carbon, just multiply by 8

3.7 * 8 = 29.6 mol Carbon

Help
Jet001 [13]

Answer:

a

Explanation:

The formation of ion occurs when an atom that is said to be neutral gains or losses electrons.

At the time it gains electrons, it is regarded that a negative ion (anion) is formed.

When it loses electron, it is regarded that a positive ion (cation) is formed.

Atomic number = No of protons and electrons occurring in a neutral atom.

Given that:

Protons = 14

electron = 18

Net Charge = no of proton - no of electron

= 14 - 18

= -4

Mass number = 14 + 15 = 29

So, the chemical symbol = Si^{-4}

For ion with

27 proton, 32 neutrons and 25 electrons

Net charge = 27 - 25

= +2

Mass number = 27 + 32 = 59

Thus, the chemical symbol = Co^{+2}
