A company want to analyze moisture content of wheat flour before using to make bread. A technician use the rapid moisture analyzer to measure the moisture content of the flour. After analyzing, the machine showed the data of 11.2%. So how much amounts of water do we need to add to the flour to increase the moisture content to 68% for breadmaking?

## EXPERT ANSWER

**Plan:** The percentage of water in the flour can be increased by adding water. The difference in the mass percent required and found must be added for every 100 grams of flour.

The required mass percent of water to make bread = 68%

The mass percent of water present in the given sample = 11.2%

The water content of flour must be increased from 11.2% to 68%

The difference in the required % and the mass % in sample = (68 – 11.2)%

= 56.8%

Therefore 56.8 g of water must be added to every 100 gram of flour.

**Answer : 56.8 g of water must be added to every 100 gram of flour.**
