The answer should be answer B. More than three times the sun. I hope this helped! :)))
Answer:
The gas pressure in both mmHg and torr is 1.00 x10⁻⁴.
Explanation:
The standard atmosphere (1 atm) equals a pressure of 760 mmHg, where mmHg represents the pressure exerted by a column of mercury 1 mm high. <u>The mmHg unit is also called the torr</u>, after the Italian scientist Evangelista Torricelli, who invented the barometer. Thus,
1 torr = 1 mmHg
and
1 atm = 760 mmHg = 760 torr
Therefore, we do the following conversion:
1 atm ------------------- 760 mmHg
1.32x10⁻⁷ atm ------- x= 1.00 x10⁻⁴ mmHg (3 significant digits)

Answer:
The molarity of the solution is 1.7 
.
Explanation:
Molarity (M) or Molar Concentration is the number of moles of solute that are dissolved in a certain volume.
The molarity of a solution is calculated by dividing the moles of the solute by the volume of the solution:
Molarity is expressed in units .
In this case, you know:
- moles of solute= 5.1
- volume= 3 L
Replacing:
Solving:
Molarity= 1.7
<u><em>The molarity of the solution is 1.7 </em></u><u><em>.</em></u>
