Answer:
it allows us to determine what substances will float and what substances will sink when placed in a liquid.
Answer:
P₂ = 1102 Kpa
Explanation:
Given data:
Initial pressure = 1000.0 Kpa
Initial temperature = 20.0°C
Final temperature = 50.0°C
Final pressure = ?
Solution:
Initial temperature = 20.0°C (20+273 = 293 K)
Final temperature = 50.0°C (50+273 = 323 K)
According to Gay-Lussac Law,
The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.
Mathematical relationship:
P₁/T₁ = P₂/T₂
Now we will put the values in formula:
1000 Kpa / 293 K = P₂/323 K
P₂ = 1000 Kpa × 323 K / 293 K
P₂ = 323000 Kpa. K /293 K
P₂ = 1102 Kpa

Explanation:
In chemistry, the formula weight is a quantity computed by multiplying the atomic weight (in atomic mass units) of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all of these products together.
Using the chemical formula of the compound and the periodic table of elements, we can add up the atomic weights and calculate molecular weight of the substance.
If the formula used in calculating molar mass is the molecular formula, the formula weight computed is the molecular weight. The percentage by weight of any atom or group of atoms in a compound can be computed by dividing the total weight of the atom (or group of atoms) in the formula by the formula weight and multiplying by 100.
