Question - Fifty grams of which of the following substances contain the greatest number of moles? Sodium carbonate Magnesium chloride Hydrogen gas

Given - Mass

Find - The greatest number of moles

Solution - The greatest number of moles are present in hydrogen gas.

For sodium carbonate

Molar mass = 106 gram/mol

Number of moles = 50/106

Number of moles = 0.47

For Magnesium chloride

Molar mass = 95 gram/mol

Number of moles = 50/95

Number of moles = 0.52

For Hydrogen gas

Molar mass = 1 gram/mol

Number of moles = 50/1

Number of moles = 50

So, the greatest number of moles are present in hydrogen gas.
