The correct statement is A. Option A is true.

Structural protein like collagen provides a structural framework and thus support to different cell structures. Hemoglobin is a protein found in red blood cells. It is made up of heme (iron) and globin(globular protein). Heme combines with oxygen to form oxyhemoglobin and transports oxygen to tissues.

SOLVE A 4.80-gram piece of magnesium displaces 2.76 mL of water when it is placed in a graduated cylinder. What is the density o

Stels [109]

Answer:

<em>Density = 1.74 gm/mL</em>

Explanation:

Given that:

Mass of piece of Magnesium = 4.80 grams

The volume displaced by this piece = 2.76mL

Let us learn about a property:

Volume of water displaced by a substance when immersed in the water is equal to the Volume of the substance itself.

So, volume of the piece of Magnesium = 2.76 mL

To find:

Density of magnesium = ?

Solution:

Let us have a look at the formula for Density of a Substance:

Density of a substance is given as the ratio of mass of substance and the volume of that mass of substance.

i.e.

$Density = \dfrac{Mass}{Volume}$

Putting the given values:

$Density = \dfrac{4.80}{2.76}\\\Rightarrow \bold{Density = 1.74\ gm/mL}$

So, the answer is:

Density of Magnesium = <em>1.74 gm/mL</em>
