Answer 2

Given:

The mass of Sodium (Na) = 230g

To Find:

The number of moles of sodium

Solution:

We know that the number of moles of a substance in a given sample having m grams of the element/compound is given by:

m / M

Here, M = The gram molar mass of the given element or compound

Since the Molar Mass of Sodium = 23g

→ The number of moles = 230 / 23

= 10 moles

10 moles of sodium implies that 10 X Na number of sodium atoms are present in the sample. Here, Na is the Avogadro's Number.

Hence, there are 10 moles of sodium in 230g of its sample.
