How many micrograms of iron were in the 6.0 ml sample of greg's blood?

1 ml of blood contains 0.5 mg of elemental iron

Therefore, 6.0 ml of a blood sample will contain: (6.0 ml * 0.5 mg)/1.0 ml = 3.0 mg

1 mg = 1000 micro gram

therefore: 6.0 ml of blood will contain 3 * 10^3 micrograms of iron

The answer is that in 6mL of blood there are 3,000 micrograms of elemental iron.

Explanation:

Hello!

Let's solve this!

The data we have are:

6mL of blood

every 1 mL of blood there is 0.5 mg of elemental iron

mg elemental iron: (0.5mg / 1mL) * 6mL = 3mg

As we are asked for micrograms, we know that 1mg = 1000micrograms

micrograms of elemental iron = 3mg * (1000micrograms / 1mg) = 3000micrograms

The answer is that in 6mL of blood there are 3,000 micrograms of elemental iron.

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
