The mass of flour =200g, and the density of flour is 520g/L,

According to the formula: mass = volume * density,

Then volume = mass/density

Substituting the data in the question, the formula can be obtained:

Volume = 200g/520g/L = 0.385l.

1L= 1000 ml

Then 0.385l = 385ml.

So 200 grams of flour is 385 ml.

Storage method of flour:

1, well ventilated flour can breathe, so it is necessary to make air circulate so that flour can be used with air.

2. Humidity Dry flour will change its water content according to the temperature and humidity of the environment. The greater the humidity, the higher the water content of flour and easy to agglomerate. The lower the humidity, the lower the water content of flour. The ideal humidity is about 60%-70%.

3. The temperature of suitable temperature storage will affect the ripening time of flour. The higher the temperature, the faster the ripening. But temperature also shortens the shelf life of flour. The recommended ideal temperature for flour storage is 18℃-24℃.

4. Clean environment Clean environment can reduce the breeding of pests and microorganisms, thus reducing the chance of flour pollution.

5. Flour without odor is a material that will absorb and store odor in the air, so there should be no odor in the surrounding environment where flour is stored.

6. It is necessary to leave the wall and the ground in order to have good ventilation, reduce moisture, reduce the pollution of insects and rats and the provisions of the law. Plastic products should be used for stacking boards. If wood products are used, care should be taken to avoid wood thorns and make them polluted.

7. First-in first-out ensures the stability of flour and reduces the artificial expiration of flour.

8, regular cleaning to reduce the breeding of insects and rats, thereby reducing the chance of flour pollution and packaging damage.
