Elza [17]

Answer:

As previously discussed, there is a connection between the number of protons in an element, the atomic number that distinguishes one element from another, and the number of electrons it has.

The molecular weight of table salt, NaCl, is 58.5 g/mol. A tablespoon of salt weighs 6.37 grams. Calculate the number of moles o
cestrela7 [59]

Answer:

The number of moles of salt in one tablespoon is = <u>0.11 mole</u>

<u>Grams </u>cancel each other.

Explanation:

<u>Moles</u> : It is the unit of quantity . It is the mass of the substance present in exactly 12g of C-12.

moles=\frac{given\ mass}{Molar\ mass}

<u>Moles Calculation:</u>

Given mass = 6.37  gram

Molar mass = 58.5 g/mol

moles=\frac{6.37}{58.5}

= 0.1088

= 0.11 mole

<u>Units calculation</u>

moles=\frac{given\ mass}{Molar\ mass}

moles=\frac{g}{g/mole}

moles=\frac{g}{g}\times mole

<u>g ang g cancels each other </u>

moles = moles

<u>Hence unit = gram (g ) cancel each other.</u>
