Calculate the pOH for a solution with h3o 2.5x10-5 g?
topjm [15]

Answer:

pOH = 9.4

Step-by-step explanation:

Mathematically;

pH + pOH = 14

pOH = 14 - pH

But pH = -log[H3O+]

From the question [H3O+] = 2.5 * 10^-5

Thus pH = -log (2.5 * 10^-5)

pH = 4.6

Thus;

pOH = 14-4.6

pOH = 9.4

A certain laundry detergent recommends \frac{1}{4}
Ray Of Light [21]

Answer:

2

Step-by-step explanation:

\frac{1}{4} a cup detergent for \frac{1}{2} a load of clothes would mean for each full load, it would take \frac{1}{2} a cup of detergent.

Thus if you have 4 load of clothes, which is 8 half loads. You can take that 8 half loads and multiply \frac{1}{4} by 8. This gives you 2 cups of detergent.

James answered 14 items correctly on a 16-item quiz. what percent did he answer correctly?
Troyanec [42]
So,

I like to simplify a fraction first.  This is what I do when I'm in a store trying to find the unit price.

\frac{14}{16}

Factor.
\frac{2*7}{2*2*2*2}

Cross out ones.
\frac{7}{2*2*2}

Multiply it out.
\frac{7}{8}

In my head, I remember that one-eighth is equal to 0.125.

So seven-eighths is equal to 0.125 times 7.
0.125 * 7 = 0.875

Convert to percent form.
0.875 --> 87.5%

James answered 87.5% of his quiz correctly.

I actually have the decimal equivalents for eighths in my head when I'm shopping.  So once I get seven-eighths, I immediately know how much that is.  I can also subtract 0.125 from 1.000 to get seven-eighths.
