Answer:

.821 g/L

Explanation:

It does not matter what the gas <u>is</u>, just the number of moles to calculate volume....

Ideal Gas Law :  

PV = n R T       R = gas constant = .082057 L-atm/(mol-K)  &  T in Kelvin units

(1.18)(V) = 5 * .082057 * (25 + 273.15)

V = <u>103.67 Liters</u>

<u />

NOW ...to calculate density, the gas  IS important...

  mole weight of NH3  (from periodic table) =  17.031 gm/mole

Density =  mass / volume    =    (5 * 17.031) / 103.67 L = .821 gm/L

At a cost of $1600/oz, how much would you have to pay for a solid cubic foot of gold?
Alex777 [14]
<h3>You will pay $ 30876800</h3>

We'll begin by calculating the mass in ounce (oz) of a cube foot (ft³) of gold. This can be obtained as follow:

<h3 />

Density of gold = 19298 oz/ft³

Volume of gold = 1 ft³

<h3>Mass of gold =?</h3>

Density = mass /volume

19298 = mass / 1

<h3>Mass of gold = 19298 oz</h3>

Finally, we shall determine the cost of 19298 oz of gold. This can be obtained as follow:

1 oz = $ 1600

Therefore,

19298 oz = 19298 × 1600

19298 oz = $ 30876800

Therefore, a solid cube foot of gold (i.e 19298 oz) will cost $ 30876800

Pharmacists sometimes measure medicines in the unit of "grains," where 1 gr = 65 mg. The label on a bottle of aspirin reads "Asp
viva [34]

Answer:

325mg of Aspririn

Explanation:

First you should note the information that the problem gives you:

- The bottle of Aspirin has 5gr (grains)

- 1gr(grain) = 65mg (miligrams)

Also, the problem is asking about how many aspirin are in 5 gr (grains), so you should use a conversion factor, as follows:

-First you should put the quantity you need to convert:

5grAspirin

-Then you write the denominator of the conversion factor that must have the same units that you want to convert, in this case gr:

5grAspirin*\frac{}{1grAspirin}

-Then you write the numerator with the units that you want to obtain and the numerical equivalence between the units, in this case:

5grAspirin*\frac{65mgAspririn}{1grAspirin}

-Finally you multiply numerators and divide by denominators:

5grAspirin*\frac{65mgAspririn}{1grAspirin}=325mgAspririn

2. Calculate the joules of energy required to heat 454.3g of water<br> frum 5.4°C to 98.6°C.
Tasya [4]

Answer:

176984.38J

Explanation:

E = mC∆T

Where E is the energy in joules

M is the mass of water

C is the specific heat capacity of water =4.184J/g°C

It is known that it will take 4.184J of energy to change the temperature of water by one degree Celsius.

∆T = 98.6°c - 5.4°c

= 93.2°c

∆H = 454.3g × 4.18J/g°C × 93.2°c

= 176984.3768

176984.38J

Fe2O3(s) + 3H2(g) → 2Fe(s) + 3H2O(1)<br> How many moles of iron can be made from 3 moles of Fe2O3?
enot [183]

<em>ANSWER - 6 MOLES OF </em><em>IRON</em>

Fe2O3(s) + 3H2(g) → 2Fe(s) + 3H2O(1)

One moles of Fe2O3 forming 2 moles of Fe

3 moles of Fe2O3 will form 2×3 = 6 moles of iron
