The natural abundances of elements in the human body, expressed as percent by mass, are oxygen (o), 65 percent; carbon (c), 18 percent; hydrogen (h), 10. percent; nitrogen (n), 3.0 percent; calcium (ca), 1.6 percent; phosphorus (p), 1.2 percent; all other elements, 1.2 percent. enter your answers in scientific notation. calculate the mass in grams of each element in the body of a 64−kg person.

O: 4.2 × 10⁴ g

C: 1.2 × 10⁴ g

H: 6.4 × 10³ g

N: 1.9 × 10³ g

Ca: 1.0 × 10³ g

P: 7.7 × 10² g

Other elements: 7.7 × 10² g

Explanation:

Natural abundances of elements in the human body (in percent by mass)

The mass of a body is 64 kg = 64 × 10³ g = 6.4 × 10⁴ g. We can calculate the mass of each element by multiplying the body weight by the mass percent of each element.

O: 6.4 × 10⁴ g × 65% = 4.2 × 10⁴ g

C: 6.4 × 10⁴ g × 18% = 1.2 × 10⁴ g

H: 6.4 × 10⁴ g × 10% = 6.4 × 10³ g

N: 6.4 × 10⁴ g × 3.0% = 1.9 × 10³ g

Ca: 6.4 × 10⁴ g × 1.6% = 1.0 × 10³ g

P: 6.4 × 10⁴ g × 1.2% = 7.7 × 10² g

Other elements: 6.4 × 10⁴ g × 1.2% = 7.7 × 10² g

c)red bank

explanation:

red bank is a borough in monmouth county, new jersey, incorporated in 1908 and located on the navesink river, the area's original transportation route to the ocean and other ports.

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.
