It is both. It is a mixture because it has two or more things mixed in it. It is a solution, because all of the components and things mixed in the milk are uniform and milk isn't chunky or discolored because of that.
Hope this helps.
Answer:
50.3mL of mercury are in 1.50lb
Explanation:
Punds are an unit of mass. To convert mass to volume we must use density (13.546g/mL). Now, As you can see, density is in grams but the mass of mercury is in pounds. That means we need first, to convert pounds to grams to use density and obtain volume of mercury.
<em>Mass mercury in grams:</em>
1.50lb * (1kg / 2.20lb) = 0.682kg = 682g of mercury.
<em>Volume of mercury:</em>
682g Mercury * (1mL / 13.546g) =
<h3>50.3mL of mercury are in 1.50lb</h3>
Answer:
0.683 moles of the gas are required
Explanation:
Avogadro's law relates the moles of a gas with its volume. The volume of a gas is directely proportional to its moles when temperature and pressure of the gas remains constant. The law is:
V₁n₂ = V₂n₁
<em>Where V is volume and n are moles of 1, initial state and 2, final state of the gas.</em>
<em />
Computing the values of the problem:
1.50Ln₂ = 5L*0.205mol
n₂ = 0.683 moles of the gas are required
<em />
Answer:
Explanation:
<u>Given Data:</u>
Volume = v = 1.12 dm³ = 1.12 L
Density of nitrogen at STP = D = 1.25 g / L
Molar mass = M = 14 * 2 = 28 g / mol
Avogadro's Number = 
= 6.023 * 10²³ mol⁻¹
<u>Required:</u>
No. of molecules = ?
<u>Formula:</u>
<u>Solution:</u>
No. of molecules = (1.25*1.12) / 28 * (6.023 * 10²³)
No. of molecules = ( 1.4 / 28 ) * 6.023 * 10²³
No. of molecules = 0.05 * 6.023 * 10²³
No. of molecules = 0.3 * 10²³
No. of molecules = 3 * 10²² molecules
