Answer:
204.8g
Explanation:
The number of moles of a substance is related to its mass and molecular mass as follows:
mole (n) = mass (m) ÷ molar mass (MM)
According to this question, 3.50 moles of sodium chloride (NaCl) is added to a food.
Molar mass of NaCl = 23 + 35.5
= 58.5g/mol
Using mole = mass/molar mass
Mass = molar mass × mole
Mass = 58.5g/mol × 3.5mol
Mass = 204.75
Mass = 204.8grams.
Therefore, 204.8grams of NaCl or common salt was added to the food.
Dilution of hcl because less no of mole of hcl would be reacting to form zncl2
Quantum numbers are the conserved quantities in the system that expresses the position of the electron. The second quantum number describes the electron subshells.
<h3>What are quantum numbers?</h3>
Quantum numbers are the energy and the position defining values of the electron in the atomic structure. There are four basic quantum numbers, principal, magnetic, azimuthal, and spin quantum.
The second quantum number (I) is the angular quantum number that describes the magnitude of the subshells (s,p, d, and f) or the type of the subshells. It is also known as the Azimuthal quantum number.
Therefore, the second quantum number shows the electronic subshells.
