Answer:

b is correct method.

Explanation:

Given that,

Volume of tank = 64 liter

We need to find the conversion liter to quarts

Using conversion

$1\ L=\dfrac{1\ l}{1.057\ quarts}$

We need to find the conversion quarts to gallons

Using conversion

$1\ quarts=\dfrac{1\ l}{4\ gallons}$

We need to find correct method

Using conversion

$64\ L=\dfrac{1\ L}{1.057}\times\dfrac{1\ gallon}{4\ quarts}$

Hence, b is correct method.

A chemist must dilute 47.2 mL of 150. mM aqueous sodium nitrate solution until the concentration falls to . He'll do this by add

erma4kov [3.2K]

Answer:

0.295 L

Explanation:

It seems your question lacks the final concentration value. But an internet search tells me this might be the complete question:

" A chemist must dilute 47.2 mL of 150. mM aqueous sodium nitrate solution until the concentration falls to 24.0 mM. He'll do this by adding distilled water to the solution until it reaches a certain final volume. Calculate this final volume, in liters. Be sure your answer has the correct number of significant digits. "

Keep in mind that if your value is different, the answer will be different as well. However the methodology will remain the same.

To solve this problem we can use the formula C₁V₁=C₂V₂

Where the subscript 1 refers to the concentrated solution and the subscript 2 to the diluted one.

47.2 mL * 150 mM = 24.0 mM * V₂

V₂ = 295 mL

And converting into L becomes:

295 mL * $\frac{1 L}{1000mL}$ = 0.295 L

Purpose of boiling chip

vichka [17]

Your attempted answer is correct.
Indeed, certain liquids, including water, could superheat when heated in a perfectly smooth container. The superheating could be interrupted by the minutest speck of dust or impurities causing a mass conversion into steam, observed physically as a bumping, causing splashes and endangering operators. Boiling chips introduce these interruptions constantly and ensure a smooth boiling of the liquid.

What is the concentration (M) of CH3OH in a solution prepared by dissolving 11.7 g of CH3OH in sufficient water to give exactly

Andrej [43]

Answer:

$3.65~M$

Explanation:

We have to remember the molarity equation:

$M=\frac{mol}{L}$

So, we have to calculate "mol" and "L". The total volume is 100 mL. So, we can do the conversion:

$100~mL\frac{1~L}{1000~mL}=~0.1~L$

Now we can calculate the moles. For this we have to calculate the molar mass:

O: 16 g/mol

H: 1 g/mol

C: 12 g/mol

$(16*1)+(1*4)+(12*1)=32~g/mol$

With the molar mass value we can calculate the number of moles:

$1.7~g~of~CH_3OH\frac{1~mol~CH_3OH}{32~g~of~CH_3OH}=0.365~mol~CH_3OH$

Finally, we can calculate the molarity:

$M=\frac{0.365~mol~CH_3OH}{0.1~L}=3.65~M$

I hope it helps!

What is the connection between Archimedes and the Mass-Volume lab

Usimov [2.4K]

Answer:

Explanation:

This question is not very clear, however, going by the key words in the question, Archimedes' principle shows a relationship between mass and volume.

Archemedes' principle states that when a body is fully or partially immersed in fluid, it is acted upon by an upward force which is equal to the weight of the fluid displaced by the body.

The volume displaced here can be determined using the formula

Density of liquid = mass displaced ÷ volume

Hence, volume = mass displaced ÷ density of liquid
