Answer:
THE NEW VOLUME AT 1 K IS 1.2 L
Explanation:
Using Charles' law which states that the volume of a given gas is directly proportional to its temperature provided the pressure remains constant.
Mathematically written as;
V1/T1 = V2/T2 at constant pressure
V1 = Initial volume = 6L
T1 = initial temperature = 5K
T2 = Final temperature = 1K
V2 = final volume = unknown
Re-arranging the equation by making V2 the subject of the equation, we obtain;
V2 = V1 T2 / T1
V2 = 6 * 1 / 5
V2 = 1.2 L
The new volume of the gas sample at 1 K is 1,2 L
The mass of 2.88 × 10²² molecules of Bi (NO₃)₃ is 678.854 grams.
<h3>What is mass?</h3>
Mass is the quantity of matter in a physical body. Mass can be calculated by dividing the molar mass by the mass of the moles of the substance.
The molar mass of Bi (NO₃)₃ is 1461.99 g/mol
The molecules here is 2.88×10²²
The number of molecules will be divided by 6.023 x 10²³
2.88×10²² / 6.023 x 10²³ = 4.781 moles
Putting the value in the equation
mole = mass/molar mass
mass = moles x molar mass
4.781 x 1461.99 = 678.854 grams
Thus, the mass of 2.88×10²² molecules of Bi (NO₃)₃ is 678.854 grams

Answer:
A.
Explanation:
In the case of a seesaw, the object at the top is the effort and the object at the bottom is the load.
Answer:
The answer is
<h2>1.0 g/cm³</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 10 g
volume = 10 cm³
It's density is
We have the final answer as
<h3>1.0 g/cm³</h3>
