Temperature increased four fold when the volume is doubled twice.
<u>Explanation:</u>
As per the Charles law, at constant pressure, without changing the pressure, the volume of the gas is in direct proportion with the temperature measured in Kelvin.
Here it is said that Volume of the sample is doubled twice so it becomes four fold and it is directly proportional to the temperature which is also increased four fold.
So the temperature of the sample increased four fold.

Answer:
Mass = 208.26 g
Explanation:
Given data:
Volume of water = 40.0 mL
Volume of water + copper = 63.4 mL
Volume of copper = ?
Density of copper = 8.9 g/cm³
Mass of copper = ?
Solution:
Volume of copper:
Volume of copper = (Volume of water + copper ) - Volume of water
Volume of copper = 63.4 mL - 40.0 mL
Volume of copper = 23.4 mL
Mass of copper:
density = mass/volume
8.9 g/cm³ = mass/23.4 mL
cm³ = mL
Mass = 8.9 g/mL × 23.4 mL
Mass = 208.26 g
The neutron is inside the nucleus
Subtract the mass of the solute from the whole solution volume.
Molarity, percent by mass, and percent by volume are all ways to represent concentration.
By dividing the number of moles by the number of liters of water utilized in the solution, we can compute the molar concentration. Here, for instance, 1.25 L of water has entirely dissolved the acetic acid. In order to determine the molar concentration, which is 0.1332 M, divide 0.1665 moles by 1.25 L. A titration is a method for figuring out the concentration of an unknown solution by using a solution with known concentration.
Finding the concentration for each sample's absorbance on the standard curve is the first step in calculating the sample concentration based on the standard curve. The next step is to multiply the concentration by the dilution factor for each sample.
