Question

В 100 г чёрной смородины содержится примерно 250 мг витамина C (1 мг=0.001 г) определи содержание витамина C в граммах на 1 кг чёрной смородины.Сколько суточных доз витамина C для взрослого человека заменяет 1 кг смородины , если 1 суточная доза составляет 0.05 г?

Answer 1

 250*0,001=0,25г-в 100г черной смородины
 1000*0,25/100=2,5г в 1кг черной смородины  
1*2,5/0,05=50суточных доз заменяет 1 кг черной смородины

Answer 2

Calculation of Vitamin C Content in Blackcurrants

To determine the content of vitamin C in 1 kg of blackcurrants, we need to convert the given information from milligrams (mg) to grams (g).

In 100 g of blackcurrants, there is approximately 250 mg of vitamin C. Since 1 mg is equal to 0.001 g, we can calculate the content of vitamin C in grams per 1 kg of blackcurrants as follows:

Content of vitamin C in 1 kg of blackcurrants = (250 mg / 100 g) * 1000 g = 2500 mg = 2.5 g.

Therefore, there is approximately 2.5 grams of vitamin C in 1 kg of blackcurrants.

Daily Vitamin C Requirement for Adults

The recommended daily intake of vitamin C for adults varies depending on factors such as age, sex, and overall health. However, a commonly recommended daily dose of vitamin C for adults is around 75-90 mg per day.

If we consider a daily dose of vitamin C to be 0.05 g (50 mg), we can calculate the number of daily doses of vitamin C that would be equivalent to the vitamin C content in 1 kg of blackcurrants:

Number of daily doses of vitamin C in 1 kg of blackcurrants = (2.5 g / 0.05 g) = 50 doses.

Therefore, consuming 1 kg of blackcurrants would provide approximately 50 daily doses of vitamin C, assuming each daily dose is 0.05 g.

Please note that individual vitamin C requirements may vary, and it is always best to consult with a healthcare professional for personalized dietary recommendations.
