Answer:
7.92 .g . mL^-1
Explanation:
Data provided in the question
Water liters = 45.5 mL
Pace of iron = 28.5 gram
Rise in the water in the cylinder = 49.1 mark
So by considering the above information
As we know that
where,
Mass = 28.5 gram
Volume = 49.1 - 45.5
= 3.6 mL
So, the density is
= 7.92 .g . mL^-1
Basically we use the density formula by dividing the mass with the volume
Explanation:
<u>Fahrenheit Scale
</u>
Fahrenheit temperature scale is the scale which is based on:
(a) For freezing point of the water, 32 °F.
(b) For boiling point of the water, 212 °F.
With interval between two being divided into equal 180 parts.
<u>
Celsius Scale
</u>
Celsius temperature scale is the scale which is based on:
(a) For freezing point of the water, 0 °C
(b) For boiling point of the water, 100 °C.
With interval between two being divided into equal 100 parts.
<u>Kelvin Scale
</u>
It denotes the triple point of water where the solid, liquid, and gas phases exist in equilibrium which is at 273.16 K.
kelvin is defined as 1/ 273.16 of triple point temperature.
<u>Answer:</u> The pressure of carbon dioxide gas is 11 atm
<u>Explanation:</u>
To calculate the pressure of gas, we use the equation given by ideal gas equation:
PV = nRT
where,
P = pressure of the gas = ?
V = Volume of gas = 25 L
n = number of moles of gas = 10 mole
R = Gas constant = 
T = temperature of the gas = 325 K
Putting values in above equation, we get:
Hence, the pressure of carbon dioxide gas is 11 atm
The liquid is blue is an example of qualitative data. Qualitative data is data that can not be represented by numbers. The volume and density are both quantitative data.
Moles = mass/molar mass
moles = 2.3
molar mass = 278
=> mass = moles*molar mass = 639.4g
