Answer:

The molar mass (or the atomic mass on the periodic table) is equal to one (1) mole of that specific element.

With compounds, just add up the molar mass of each element in the compound. Make sure you have the right number of each element as well (see the subscripts attached to the element symbol)

***Diatomic elements (when by themselves) are ALWAYS is pairs

Example:

H₂O = 2 hydrogen + 1 Oxygen

H has a molar mass of 1.008

O has a molar mass of 15.999

since we have 2 hydrogen, we multiply it's molar mass by 2

now we add the masses

1 mole of  H₂O = 18.015 g of H₂O

Question 1

The correct statement is D. The mental region is superior to the nasal region.

The different terms in the statements are anatomical terms. We use them to describe the regions and locations of organs.

<h3>Why are the other statements incorrect</h3>
  • The pubic region is inferior to the pelvic region: inferior means is lower. However, the pubic region is higher than the pelvic region.
  • The olecranon region is distal to the carpal region: we describe organs and bones in relation to the nearest parts to the axis of the body. In other words, we describe things from proximal (to the column and head) to distal. So, the carpal is distal to the olecranon.
  • The heart lies dorsal to the vertebral column: dorsal means behind. The heart lies ventral to the column. In other words, towards the front of it.
  • The sternal region is lateral to the axillary region: we describe locations from proximal to distal, so the axillary region is lateral to the sternal region.

In conclusion, the correct option is: The mental region is superior to the nasal region because the mental region is the one that is above the nasal one in the skull.
