140 s. It would take 140 s to swim 0.150 mi .

<em>Step 1</em>. Convert the <em>time to seconds</em>

Time = 14 min × (60 s/1 min) + 34.56 s = 840 s + 34.56 s = 874.56 s

<em>Step 2</em>. Convert <em>miles to metres </em>

Distance = 0.150 mi × (1609.3 m/1 mi) = 241.4 m

<em>Step 3.</em> Calculate the <em>time to swim 241.4 m</em>

Time = 241.4 m × (874.56 s/1500 m) = 140 s

(<em>As of 2012, the men’s freestyle record for 1500 m was 14:31.02</em>.)

A very new item just arrived in the market. It is very good for construction, and other things. Now, this item has chemicals, an
VMariaS [17]

Answer: 4,000 grams of NaCI

Explanation:

We know that there are 400g of NaCI in one drop.

This bottle has 10 drops of this item.

So, we have to multiply the amount of NaCI in a drop by the amount of drops.

400 x 10 = 4,000.

The answer to the question is 4,000. Hope this helps!

If 25.0 mL of 0.100 M Ca(OH)2 is titrated with 0.200 M HNO3, what volume of nitric acid is required to neutralize the base?
Troyanec [42]

Answer:

25 mL

Explanation:

The reaction that takes place is:

  • Ca(OH)₂ + 2HNO₃ → Ca(NO₃)₂ + 2H₂O

First we<u> calculate how many Ca(OH)₂ moles</u> were spent in the titration:

  • 25.0 mL * 0.100 M = 2.5 mmol Ca(OH)₂

Then we <u>convert Ca(OH)₂ moles into HNO₃ moles</u>, using the <em>stoichiometric ratio</em>:

  • 2.5 mmol Ca(OH)₂ * \frac{2mmolHNO_3}{1mmolCa(OH)_2} = 5.0 mmol HNO₃

Finally we <u>calculate the volume of required nitric acid solution</u>, using the <em>concentration</em>:

  • 5.0 mmol ÷ 0.200 mmol/mL = 25 mL
