Question

массовая доля костей человека составляет 20 % от общей массы организма.На долю фосфата кальция входящего в состав костей приходится так же 20 % от массы костей. Зная свой вес рассчитайте сколько кг фосфата кальция содержится в вашем организме. Сколько кг кальция содержится в нем? мой вес - 72 кг

Answer 1

1/5 от 1/5 = 1/25, следовательно 1/25 * 72 = 2.88кг

Answer 2

Mass of Bones in Human Body

According to the information provided, the mass of bones in the human body constitutes 20% of the total body mass..

Calcium Phosphate Content in Bones

The phosphate content of calcium in bones also accounts for 20% of the bone mass..

Calculation of Calcium Phosphate and Calcium Content

To calculate the amount of calcium phosphate and calcium in your body, we need to know your weight, which you mentioned is 72 kg.

To calculate the amount of calcium phosphate in your body: - Multiply your weight (72 kg) by the percentage of bone mass (20%): 72 kg * 0.20 = 14.4 kg.

Therefore, approximately 14.4 kg of calcium phosphate is present in your body.

To calculate the amount of calcium in your body: - Since calcium phosphate accounts for 20% of the bone mass, we can assume that calcium also accounts for the same percentage. - Multiply the weight of calcium phosphate (14.4 kg) by the percentage of calcium in bones (20%): 14.4 kg * 0.20 = 2.88 kg.

Therefore, approximately 2.88 kg of calcium is present in your body.

Please note that these calculations are based on the given information and may not be exact. It's also important to remember that individual variations may exist.
