Calculate  the  mole  of  glucose  and  water
 The  moles  of water =158g/18g/mol=8.778 moles
moles of  glucose =52.8g/180g/mol=0.293 moles
determine  the mole  fraction  of  the  solvent
that  is   x solvent = 8.778/ (8.778+0.293)=0.9677
use  the  Raults  law  to  determine  the  vapor  pressure
100  degree  of  water  has   a  vapor  pressure  of  760 mmhg
p solution=(x  solvent) (p^o solvent)
p solution=0.9677 x760 =735.45 mmHg

Harrizon [31]

Answer:

So sorry if I was wrong but I think it's B. Because from the source states,

https://socratic.org/questions/which-group-on-the-periodic-table-is-the-least-reactive-why

"The least reactive elements are those who have a full outermost valence shell ie they have 8 electrons in the outer shell so elements such as helium, neon, radon or the transition elements."

If the (H+) is 2.1×10^-12 MHCIO4, What is the PH? is the solution ACIDIC, BASIC or NEUTRAL.​
Lilit [14]

Explanation:

The pH of a substance can be found by using the formula

pH =  -  log[ H^{ + }  ]

where [ H+ ] is the hydrogen ion concentration in the substance

From the question

[ H+ ] = 2.1 × 10-¹² M

To find the pH substitute the value into the above formula

We have

pH =  -  log(2.1 \times  {10}^{ - 12} )  \\  = 11.6777807 \:  \:  \:  \:  \:  \:

We have the answer as

<h2>pH = 11.7 </h2>

The solution is basic since it lies in the basic region that is from 8 to 14

Hope this helps you
