5. What volume of silver metal will weigh exactly 4500.0 g. The density of silver is 20.5 g/cm.
Vitek1552 [10]

Answer:

The answer is

<h2>219.5 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

mass = 4500 g

density = 20.5 g/cm³

We have

volume =  \frac{4500 }{20.5}  \\  = 219.51219...

We have the final answer as

<h3>219.51 mL</h3>

Hope this helps you

How many atoms of carbon are in 24 grams of carbon?
Mamont248 [21]
(3 grams of carbon) x (1 mole of carbon/12 grams ) =3/12 = 1/4 of a mole of carbon. Then... ( 1/4 of a mole) x (6.02 x 10^23 atoms/mole) = approximately 1.5 x 10^23 atoms.

How many tons of zinc can be obtained from 976 tons of zinc ore that is 78.0% zinc carbonate?
kramer
First, calculating the amount of zinc carbonate by multiplying the given mass of the ore by the percent zinc carbonate. 
                          mass of zinc carbonate = (976 tons)(0.78) 
                                                       = 761.28 tons
Then, calculate for %Zn in zinc carbonate
                           %Zn = ((65.38) / (125.39)) x 100%
                                          % Zn = 52.141%
tons of Zn from the sample,
                           mass of Zn = (761.28 tons)(0.52141)
                                              = 396.94 tons Zn

Stells [14]

Answer: 25%

Explanation: According to the Florida Industrial and Phosphate Research Institute, Florida’s phosphate mining  accounts for about 75% of the phosphate used in the United States, as well as about 25% phosphate used around the world.  Although first mined in England in 1847, and used as fertilizer, In  1881,  a civilian employee, J Francis Le Baron discovered Phosphate pebbles in peace river, and then, a hard rock phosphate district was discovered in north central Florida after that which began the Phosphate mining industry in Florida. Phosphorus rock  supplies the phosphorus element in the fertilizer mix of nitrogen-phosphorus-potassium that is used as fertilizer to aid in growth of plants.
