Answer:
0.00508368 grams
Explanation:
From the question we are told that the daily allowance for infants and children is 8.00 × 10⁻⁶ mole of copper per kiogram of body weight.
Since this value is given in moles, we have to convert it to mass
Molar mass of a compound = mass in grams / no of moles of the compound.
So, Molar mass of copper = 63.546
No of moles of copper per kg = 8.00 × 10⁻⁶ mole
63.546 = mass/ 8.00 × 10⁻⁶ mole
Cross multiply
Mass of copper per kg body weight = 8.00 × 10⁻⁶ × 63.546
= 0.000508368 grams
Hence, the daily allowance of copper required for infants or children per kg of weight = 0.000508368 grams.
For a 10 kg infant this is calculated as:
If 1 kg per weight of an Infant = 0.000508368grams
10 kg =
We cross multiply
10 kg × 0.000508368 grams
= 0.00508368 grams.
Therefore, the mass of copper required per day for a 10 kg child is 0.00508368 grams
Answer:
systole answer is number 1 and diastole is no 2
Answer:
The correct answer is a. True
Explanation:
The resting heart rate for a normal adult is between 50 to 90 beats per minute. Resting heartbeat below 50 is possible in persons who are very good athletes. A more cardiovascular fitness is seen in good athlete and they can have a resting heart rate near to 40.
If a normal resting heart rate falls from 60 that condition is known as bradycardia. Mostly old people are more prone to it. Tachycardia is a medical condition in which a person's resting heartbeat reaches above 100.
Both the condition bradycardia and tachycardia shows the problem related to heart and require medical attention.
