What is the poH of a<br> 4.8 x 10-10 M H+ solution?
stiks02 [169]

Answer: pOH = 4.68

Explanation:

pOH = 14 - pH

pH = - Log [H+]

= - Log [4.8 x 10^-10]

= -(-9.32)

pH =+9.32

Therefore, pOH= 14 - 9.32

= 4.68

a sample of mass 6.814grams is added to another sample weighing 0.08753 grams. the subsequent mixture is then divided into exact
Alexxx [7]

Answer:

Final\ Mass = 17.560943085g

Explanation:

Given

Sample\ Mass = 6.814g

Additional\ Mass = 0.08753g

Yield = 7.6335

Required

Determine the final mass

First we need to determine the total mass after the sample mass is added to an additional sample;

Total\ Mass = Additional\ Mass + Sample\ Mass

Total\ Mass = 0.08753g + 6.814g

Total\ Mass = 6.90153g

Next, divide the total mass by 3

New\ Mass = \frac{Total\ Mass}{3}

New\ Mass = \frac{6.90153g}{3}

New\ Mass = 2.30051g

The final mass is calculated as follows;

Final\ Mass = New\ Mass * Yield

Final\ Mass = 2.30051g * 7.6335

Final\ Mass = 17.560943085g

<em>Hence, the final mass is 17.560943085g</em>
