The new volume of the gas is 144 mL.
<u>Explanation:</u>
At STP, the temperature is 273 K an pressure is 1 atm.
1 atm=101kPa
Given that initial volume V1=36 mL
Initial pressure P1=1atm=101 kPa
Final pressure P2=25.3kPa
We have to determine the final volume V2
According to Boyle's law
=144 mL
Final volume =144mL
True, its called sublimation. (vice versa as well)
Answer:
1.896 mol Cl
Explanation:
- Because the chloride is 67.2% chlorine by mass, i<u>n a 100 g sample of this compound, we would have 67.2 g of chlorine.</u>
With that information then we can calculate <u>the moles of chlorine</u> present in 67.2 g, using its atomic mass (accurate to 4 sig. fig. as the exercise asked):
67.2 g Cl ÷ 35.45 g/mol = 1.896 mol Cl
The number of pounds present in 2.72 kg of Mastiff puppy is 5.996 pounds
<h3>What is weight?</h3>
Weight can be defined as the gravitation pull on a body. or it can also be defined as the product of the mass of a body and its acceleration due to gravity.
<h3>Units of weight</h3>
weight has several units and they include
- Newton
- pounds
- ounces
- Tons.
These units can be converted.
From the question,
If
But,
Then,
Therefore,
- 2.72 kg of Mastiff = (2720/453.6) pounds of average Mastiff = 5.996 pounds
Hence, The number of pounds present in 2.72 kg of Mastiff puppy is 5.996 pounds.
