Answer:

Explanation:

according to the balance chemical equation

2 moles of c6h14 give us 14 moles of H2O

now mass(in gram) of 2 moles of C6H14 is

moles=mass/molar mass

mass=molar mass*moles

molar mass of C6H14 is 86 therefore

mass=86*2=172

now mass of 14 moles of water is

mass=molar mass*moles

molar mass of water is 18

mass=18*14=252

from the above calculations we conclude that  

172 grams of C6H14 produce 252 grams of water

so 1.28 grams of C6H14 produce =252*1.28/172=1.87 grams of water

result is that 1.28 grams of C6H14 produced 1.87 grams of water

If the density of mercury is 13.6g/ml, how many ml of mercury are in 1,000 g of mercury?
Illusion [34]

Answer:

<h2>73.53 mL</h2>

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

volume =  \frac{mass}{density} \\

From the question we have

volume =  \frac{1000}{13.6}  \\  = 73.52941...

We have the final answer as

<h3>73.53 mL</h3>

Hope this helps you

What is the simplest formula of a compound if a sample of the compound contains 0.221 mol X, 0.442 mol Y, and 0.884 mol Z? chemP
Gnoma [55]

Answer:

XY₂Z₄

2.35 mol Z

Explanation:

A sample of the compound contains 0.221 mol X, 0.442 mol Y, and 0.884 mol Z. We can find the simplest formula (empirical formula) by <em>dividing all the numbers of moles by the smallest one</em>.

X: 0.221/0.221 = 1

Y: 0.442/0.221 = 2

Z: 0.884/0.221 = 4

The simplest formula is XY₂Z₄.

The molar ratio of X to Z is 1:4. The moles of Z in a sample that contained 0.588 moles of X is:

0.588 mol X × (4 mol Z/1 mol X) = 2.35 mol Z

2. Matt went to his friend’s party. He ate a big meal and drank a keg of beer. He felt heartburn after the meal and took Tums to
evablogger [386]

Answer:

390.85mL

Explanation:

Step 1:

Data obtained from the question.

Initial pressure (P1) = 780 torr

Initial volume (V1) = 400mL

Initial temperature (T1) = 40°C = 40°C + 273 = 313K

Final temperature (T2) = 25°C = 25°C + 273 = 298K

Final pressure (P2) = 1 atm = 760torr

Final volume (V2) =?

Step 2:

Determination of the final volume i.e the volume of the gas outside Matt's body.

The volume of the gas outside Matt's body can be obtained by using the general gas equation as shown below:

P1V1/T1 = P2V2/T2

780 x 400/313 = 760 x V2 /298

Cross multiply to express in linear form

313 x 760 x V2 = 780 x 400 x 298

Divide both side by 313 x 760

V2 = (780 x 400 x 298) /(313 x 760)

V2 = 390.85mL

Therefore, the volume of the gas outside Matt's body is 390.85mL
