Answer:

The mass of N a H C O 3 present is 2.431 g

Explanation:

The sample contains 57.2 % N a H C O 3 by mass.

To find the mass of N a H C O 3 in the sample, we need to find what the equivalent of 57.2 %.

Mass of N a H C O 3 = Percentage Composition * Mass of sample

Mass of N a H C O 3 = 57.2 / 100 * 4.25

Mass of N a H C O 3 = 2.431 g

The mass of N a H C O 3 present is 2.431 g

Explanation:

The reasons that islands formed are still growing is simply because newer materials are being added to them.

A growing earth is as a result of addition of more materials arising from the mantle.
Generally, Volcanic islands forms as a result of magma that reaches the surface or ocean floor from deeper part of the earth.
This usually occurs in places around a plate boundary where materials upwells from the asthenosphere or shallow crustal melting.
As more materials are being melted, more also reaches the surface and continues to make the Island grow.
