Step 1

Given, mass of a sample = 58.9 g

The sample contains 47.9 percent calcium carbonate by mass.

The mass of calcium carbonate in the sample can be calculated as: help_outlineImage TranscriptioncloseMass of calcium carbonate = 47.9% x Mass of sample 47.9 X Mass of calcium carbonate 58.9 g 28.2131 g 100 fullscreen
Step 2

This means that 28.2131 g is present in 58.9 g of the sample.

Therefore, grams of the sample in 15.1 g of calcium carbo... help_outlineImage Transcriptionclose28.2131 g of C2CO3 is present in 58.9 g of sample 58.9 1 g of CaCO3 is present in 28.2131 of sample 58.9 x 15.1 g of sample . 15.1 g of CaCO3 is present in 28.2131 - 31.52 g of sample fullscreen
