How is speed determined?
enot [183]

Speed equals distance divided by time (Speed=Distance/Time).

For example if it takes someone three minutes to go three miles their speed is one mile a minute.

Find the density of an object that has a mass of 5 kg and a volume of 50 cm3
serg [7]
Density = mass/volume. 5000/50= 100 grams per cubic centimeter. No substance on Earth has anywhere near that density. Tops is about 20 for osmium and gold.

Calculate the total number of Cl atoms in 150mL of liquid Ccl4 (d=1.589g/mL)<br>​
GalinKa [24]

Answer:

The total number of Cl atoms in 150mL of liquid CCl4 is 3.73*10²⁴.

Explanation:

First you must determine the mass of CCL4 present in 150mL of CCl4. Density is a quantity that allows us to measure the amount of mass in a certain volume of a substance, whose expression for its calculation is the quotient between the mass of a body and the volume it occupies:

density=\frac{mass}{volume}

In this case, the density value of d = 1.589 g/mL. Then, being the volume equal to 150 mL, the value of the mass can be calculated as:

mass= density*volume

mass=1.589 g/mL * 150 mL

mass= 238.35 g

Now, being the molar mass of CCl4 154 g/mol, the number of moles that 238.35 g represents is calculated as:

moles=\frac{238.35 g}{154 \frac{g}{mol} }

moles= 1.55

1 mole of the compound CCl4 contains 4 moles of Cl. Then, using a simple rule of three, it is possible to calculate the number of moles of Cl that 1.55 moles of CCl4 contain:

moles of Cl=\frac{1.55 moles of CCl_{4} *4 moles of Cl}{1 mole of  CCl_{4} }

moles of Cl= 6.2

Avogadro's Number or Avogadro's Constant is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023*10²³ particles per mole. Avogadro's number applies to any substance.  In this case it can be applied as follows: if 1 mole of Cl contains 6.023*10²³ atoms, 6.2 moles of Cl how many atoms does it contain?

atoms of Cl=\frac{6.2 moles*6.023*10^{23} atoms}{1 mole}

atoms of Cl= 3.73*10²⁴

<u><em>The total number of Cl atoms in 150mL of liquid CCl4 is 3.73*10²⁴.</em></u>

Gravity on the surface of the moon is only 1/6 as strong as gravity on the Earth. What is the weight of a 19 kg object on the Ea
Dahasolnce [82]

The weight of anything in any place is

         (mass of the thing) x (acceleration of gravity in that place).

-- On Earth, the acceleration of gravity is about  9.807 m/s²

Weight of 19 kg of mass is  (19 kg) x (9.807 m/s²) =  <em>186.3 newtons</em>


-- On the Moon, the acceleration of gravity is about 1.623 m/s²

Weight of the same 19 kg of mass is  (19 kg) x (1.623 m/s²) = <em>30.8  newtons</em>
