A scuba tank contains a mixture of oxygen (O2) and nitrogen (N2) gas. The oxygen has a partial pressure of PO2=5.62MPa. The tota
dmitriy555 [2]

Answer:

21.16 MPa

Explanation:

Partial pressure of oxygen = 5.62 MPa

Total gas pressure = 26.78 MPa

But

Total pressure of the gas= sum of partial pressures of all the constituent gases in the system.

This implies that;

Total pressure of the system = partial pressure of nitrogen + partial pressure of oxygen

Hence partial pressure of nitrogen=

Total pressure of the system - partial pressure of oxygen

Therefore;

Partial pressure of nitrogen= 26.78 - 5.62

Partial pressure of nitrogen = 21.16 MPa

Calculate the ph of a solution having [OH-] = 8.2 x 10 ^-8M
egoroff_w [7]

Answer:

<h2>6.91 </h2>

Explanation:

To find the pH we must first find the pOH

The pOH can be found by using the formula

pOH = - log [ {OH}^{-} ]

We have

pOH =  -  log(8.2 \times  {10}^{ - 8} )  \\  = 7.086186...

pOH = 7.09

Next we use the equation

pH = 14 - pOH

We have

pH = 14 - 7.09

We have the final answer as

<h3>6.91</h3>

How many moles are in 4.01x10^24 particles?
skelet666 [1.2K]

Answer:

6.64

Explanation:

so moles

\frac{number  \: of \: \: particles \: }{6.02 \times  {10}^{23} }

then do =4.01×10^24/6.02×10^23

you get the answer as 6.6445 u only need to write the answer to

3.S.F 6.64 moles

hope this make sense :)
