Answer: Option (B) is the correct answer.

Explanation:

When a liquid changes into vapors or gas then this process of change is known as evaporation.

A mixture in which solute particles completely dissolve in even composition throughout the solvent then it is known as homogeneous mixture.

For example, when salt is dissolved in water then upon heating it water can be evaporated and crystals of sodium chloride can be obtained.

Whereas screening method is used in the discovery of a drug and it a scientific experimentation method.

When particles of a mixture are separated by spinning then this process is known as centrifugation.

When a magnetic force is used to separate magnetic particles present in a mixture then this process is known as magnetic separation.

Thus, we can conclude that evaporation is the separation method would be most successful in separating the components of a homogeneous mixture.

What mass of solute should you measure out in order to make 1,000 mL of a 0.3 M solution of magnesium phosphate Mg3(PO4)2?
vivado [14]

Hey there !

Molecular Weight: 262.86 g/mol

Volume in liters : 1,000 mL => 1,000 / 1000 => 1 L

Number of moles of solution :

number of moles = volume x molarity

number of moles = 1 x 0.3  => 0.3 moles

Therefore:

1 mole Mg₃(PO₄)₂ ------------------- 262.86 g

0.3 moles ----------------------------- mass of Mg₃(PO₄)₂  ??

mass of Mg₃(PO₄)₂ = 0.3 x 262.86 / 1

mass of Mg(PO₄)₂ => 78.858 g

Hope this helps!

At 600. K how many moles of gas are in a 1.00 L cylinder at atmospheric pressure?
Anton [14]

Answer:

0.02moles

Explanation:

To answer this question, the general gas law equation is used. The General gas law is:

Pv = nRT

Where; P = standard atmospheric pressure (1 atm)

V = volume (L)

n = number of moles

R = Gas law constant

T = Temperature

For this question; volume = 1.00L, atmospheric pressure (P) = 1 atm, R = 0.0821 L-atm / mol K, T = 600K, n = ?

Therefore; Pv = nRT

n = PV/RT

n = 1 × 1/ 0.0821 × 600

n = 1/49.26

n = 0.0203moles

Hence, there are 0.02 moles of gas.
