What mass of sodium hydroxide has the same number of oxygen atoms as 100.0 g of ammonium carbonate?

Interpretation Introduction

Interpretation:

The mass of NaOH has same number of Oxygen atoms as 100g of (NH4)2CO3 should determined.

Concept introduction:

Mole:

The ratio between mass of the sample taken and molar mass of compound to give a mole of the analyte present in taken gram of sample.

Mole=MassMolarmass

Explanation

To calculate the mass of NaOH has same number of Oxygen atoms as 100g of (NH4)2CO3.

Molar mass of (NH4)2CO3 is 96.09g/mol

Mole of (NH4)2CO3 present in 100.0gof(NH4)2CO3 is,

=100.0g96.09g=1.04moles

Here (NH4)2CO3 three tomes much of oxygen than NaOH so the mole of three time mole of NaOH contains 1 mole of oxygen in (NH4)2CO3.

Molar mass of NaOH is 40.0g/mol

Mole ofNaOH=3×1
