Why is the average atomic mass of an element referred to the "molar mass" of an element?

Answer: “Atomic mass is expressed in atomic mass units while molar mass is expressed in grams.”

It’s true that atomic mass is expressed in atomic mass unity, called u.m.a. or dalton, but surely molar mass is expressed in the same unity too and not in grams. For example the atomic mass of hydrogen is 1.008 u.m.a.. The molar mass of water (H2O) is the sum of 2 atomic mass of hydrogen and 1 atomic mass of oxygen: 1.008x2+16=18.016 u.m.a.

Explanation:  The unit of atomic mass and molar mass is the same and it corresponds to 1/12 of the mass of the nucleus of the carbon isotope 12. Therefore both are not masses but pure dimensionless numbers. When I say that sodium (Na) has atomic mass 22.997 u.m.a., I simply say that sodium atoms weighs 22.997 time more than the atomic mass unity. When I say that CO2 has a molecular mass of 44.01 u.m.a. I say that the CO2 molecule weighs 44.01 time more than the atomic mass unity.

To move from the atomic mass to the gr-atoms, used for single atoms, or moles (gr-moles) used for molecules, both used in the stoichiometric calculations, you have simply to use the atomic mass and the molecular mass and put the dimension in grams. For the moles you can use lower dimensions (millimoles, micro moles, etc.) and higher dimensions (kilomoles, tonmoles, etc.).

svet-max [94.6K]

We have to convert 0.18 km into feet

First, we need to know the conversions:

1 inch = 2.54 cm (exact)

1 pound = 454 g

1 Liter = 1.0b quarts

1 feet = 12 inches

1 galion = 4 quarts

1 pound = 16 ounces

0.18 km x (1 feet/12 inches) x (1 inch/2.54cm) x (1000 m/1 km) x (100 cm/1 m) = 590 ft

Answer: 590 ft (2 significant figures)

Examples of energy being used around your class room
SpyIntel [72]
In the average classroom. You have AC and DC energy that flows through the wires and powers your computers, phones, projector (if you have one), the light-bulbs in the ceiling or around the room. Their is potential energy when an object is at rest for example your pencil or desk, There is Kinetic energy when objects are moving for example if you walk around or something is rolling around. You yourself is an example of energy.<span />

victus00 [196]

One can expect to find the greatest amount of hydrolyzed pth when, entering the nephrons.

<h3><u>Where would one expect to find the greatest amount of hydrolyzed pth ?</u></h3>
  • In a healthy person, the body will respond by excreting calcium and PTH byproducts if plasma calcium is higher than usual. The nephron is a solid predictor since the kidneys are where excretion takes place.
  • A) is false since PTH, not the hydrolyzed compounds, is produced by the parathyroid gland.
  • One would anticipate significant amounts of PTH exiting the liver rather than entering since the liver hydrolyzes PTH.
  • The largest concentration would still be in the nephrons, even if it is possible that some hydrolysis products will be in systemic circulation (and therefore penetrate the bones).
  • The cortical bone, which is the outermost part of the bone, has a network of small tubes called haversian canals that let blood vessels and nerves to pass through them.
