Calculate the formula unit mass of CaCl2​

Chemistry
1 answer:
melomori [17]3 years ago
3 0
Formula unit mass is defined as the sum of the mass of all the atoms each multiplied its atomic masses that are present in the empirical formula of a compound. It is expressed in amu.

Atomic mass of calcium = 40 amu

Atomic mass of chlorine = 35.5 amu

Formula mass of CaCl2 = (1 x 40) + (2 x 35.5) = 111amu.

Chemical and physical properties for Benzoyl peroxide?
pishuonlain [190]
  1. <u>Physical Properties :</u>
  • It is a crystalline colorless solid structure it is soluble in solution such as ether, alcohol, and chloroform but insoluble in water.
  • It is dangerous when it is dry and is very volatile and decomposes when it reaches 103 c.

    2. <u>Chemical Properties :</u>

  • It causes swelling of the skin and undergoes free radical products that are highly reactive.
  • It is irritant when it contacts the skin it breaks down to yield oxygen and benzoic acid.

<u>Explanation:</u>

  • Benzoyl Peroxide is widely used in industry at large scale.
  • It is formed when there is a reaction between hydrogen peroxide and benzoyl chloride.
  • Benzoyl peroxide is used in bread and cheese as the bleaching agent and also used in cosmetics as hair coloring.  
  • Because of its antibacterial property and a peroxide group it is applied to the human skin to treat acne.

1.40 m3 is how many mL
Zarrin [17]

\LARGE{ \boxed{ \rm{ \pink{Solution:}}}}

We know, 1 m³ of space can hold 1000 l of the substance.

⇛ 1 m³ = 1000 l----(1)

And, 1 l is 1000 times more than 1 ml

⇛ 1 l = 1000 ml------(2)

So, From (1) and (2),

⇛ 1 m³ = 1000 × 1000 ml

⇛ 1m³ = 1000000 ml

We had to find,

⇛ 1.40 m³ = 1.40 × 1000000 ml

⇛ 1.40 m³ = 140/100 × 1000000 ml

⇛ 1.40 m³ = 1400000 ml

⇛ 1.40 m³ = 14,00,000 ml / 14 × 10⁵ ml / 1.4 × 10⁶ ml

☃️ <u>So</u><u>,</u><u> </u><u>1.40</u><u> </u><u>m</u><u>³</u><u> </u><u>=</u><u> </u><u>1</u><u>4</u><u> </u><u>×</u><u> </u><u>1</u><u>0</u><u>⁵</u><u> </u><u>m</u><u>l</u><u> </u><u>/</u><u> </u><u>1.4</u><u> </u><u>×</u><u> </u><u>10</u><u>⁶</u><u> </u><u>ml</u><u>.</u>

What volume does 76 g of fluorine gas occupy at stp?
solong [7]
<span>2 * 22.4 = 44.8 liters (if using pre 1982 standard) 2 * 22.7 = 45.4 liters (if using 1982 and later standard) First, let's determine how many moles of F2 we have. Atomic weight fluorine = 18.998403 Molar mass F2 = 2 * 18.998403 = 37.996806 g/mol Moles F2 = 76 g / 37.996806 g/mol = 2.000168119 mol Now we have a minor problem. What definition of STP are you using? Up until 1982, STP was defined as 0°C and 1 atmosphere (101.325 kPa) From 1982 and later, STP was defined as 0°C and 100 kPa Because of the difference in pressure between the two different definitions of STP, the molar volume of a gas is 22.414 liter/mol using the pre-1982 definition and 22.711 liter/mol using the 1982 and later definition. So you get to choose which of the following 2 answers. 2 * 22.4 = 44.8 liters (if using pre 1982 standard) 2 * 22.7 = 45.4 liters (if using 1982 and later standard) Unfortunately there's still a large number of text books in use using the standard that should have been obsolete 35 years ago.</span>
