<h3>Explanation:</h3>

<u>Step 1: Define</u>

[Given] 1.5 atm

[Solve] mmHg

<u>Step 2: Identify Conversions</u>

1 atm = 760 mmHg

<u>Step 3: Convert</u>

  1. [DA] Set up:                                                                                                     \displaystyle 1.5 \ atm(\frac{760 \ mmHg}{1 \ atm})
  2. [DA] Multiply/Divide [Cancel out units]:                                                        \displaystyle 1140 \ mmHg

<u>Step 4: Check</u>

<em>Follow sig fig rules and round. We are given 2 sig figs.</em>

trapecia [35]

Answer:

d Rubidium

The atomic radius of an atom is the distance from the center of the nucleus to its outermost electron.

The atomic radius of elements varies in the periodic table, it increases as you go down in a group and decreases along the period from left to right.  

All the elements listed: Hydrogen, Sodium, Lithium and Rubidium belong to the same group in the periodic table (group 1), Since atomic radius increases from top to bottom in a group, Rubidium has the largest atomic radius.

Kobotan [32]

Answer:

0.21 M

Explanation:

Molarity is the calculation of the solution in which the number of solute per liter of the solutions. It is the most common measurement unit that is used to measure the concentration of the solution.

The molarity is the unit that is used to measure or calculate the volume of the solvent. The amount of solvent is used in the chemical reaction.

The amount of the two solvent in the same quantity is measured by the formula called c1v1 and c2v2.
