Question

2Na +IcI2 24g NaCl ? g Na (Molar Mass)1 (1-35,57Na=23

Answer 1

`\text{ 4g NaCl }\rightarrow\text{ 1.573g Na}`

Step-by-step explanation:

Here, we want to know the mass of sodium produced from 4 g sodium chloride

From what we have two moles of sodium chloride was produced from 2 moles of sodium

Now,we need to get the number of moles of sodium chloride present in 4g of it

To get that, we have to divide the mass of sodium chloride by its molar mass

The molar mass of sodium chloride is 58.5 g/mol

The number of moles is thus:

`(4)/(58.5)\text{ = 0.06838 mol}`

This is the same as the number of moles of sodium

Now,to get the mass of sodium, we have to find the product of the number of moles of sodium and its atomic mass

Mathematically, we have that as:

`0.06838\text{ }*\text{ 23 = 1.573 g}`
