weight=mass x gravitational field strength
hence weight of book=1.5x9.81
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.

Answer:
NaCl has a smaller lattice energy compared to CaO
Explanation:
We have remember that lattice energy increases as the size of the ions in the ionic solid decreases. According to Oxford dictionary; lattice energy is "a measure of the energy contained in the crystal lattice of a compound, equal to the energy that would be released if the component ions were brought together from infinity."
We know that the larger the magnitude of charge on a cation the smaller in size the cation is and the size of anions increase from left to right in the periodic table. Hence Ca^2+<Na^+ and O^2- < Cl^-. Therefore the lattice energy of CaO is greater than that of NaCl.
1 mol of any particles has 6.02 * 10 ²³ particles.
If we look at 1 NH3 (1 mol NH3 or 1 molecule NH3), we can see that 1 molecule NH3 has 1 atom of N and 3 atoms of H; also 1 mole of NH3 has 1 mole of N atoms and 3 moles of H atoms.
So, 1 mol of NH3 has 1 mol of N atoms,
and 2.79 mol NH3 have 2.79 mol of N atoms.
2.79 mol of N atoms* 6.02 * 10 ²³ N atoms/ 1 mol N atoms = 1.68*10²⁴ N-atoms
Answer is 1.68*10²⁴ N-atoms.
A fan pulls in air from the surrounding area, which typically has high moisture levels.
When the air passed through the dehumidifier , it touches the cooling coils , which in turn pull moisture from the air by lowering temperature.
