Physical property of matter found between comparing mass to volume or basically dividing mass by volume is density.
Answer: Temperature and number of moles are the conditions which remain constant in Boyle's law.
Explanation:
Boyle's law states that at constant temperature the pressure of a gas is inversely proportional to the volume of gas.
Mathematically, it is represented as follows.
As equation for ideal gas is as follows.
PV = nRT
And, at constant temperature the pressure is inversely proportional to volume which also means that number of moles are also constant in Boyle's law.
Thus, we can conclude that temperature and number of moles are the conditions which remain constant in Boyle's law.
Molar mass FeTiO3 => 151.7102 g/mol
atomic mass Ti => 47.867 u
% ( atomic mass Ti / molar mass FeTiO3 ) x 100
= ( 47.867 / 151.7102) x 100
= 0.3155 x 100
= 31.55 % of Ti
hope this helps!
Answer:
There are three rules on determining how many significant figures are in a number:
Non-zero digits are always significant.
Any zeros between two significant digits are significant.
A final zero or trailing zeros in the decimal portion ONLY are significant.
<u>Answer:</u> The order of increasing boiling points follows:
<u>Explanation:</u>
The expression of elevation in boiling point is given as:
where,
= Elevation in boiling point
i = Van't Hoff factor
= change in boiling point
= boiling point constant
m = molality
For the given options:
- <u>Option 1:</u> 0.050 m
Value of i = 3
So, molal concentration will be =
- <u>Option 2:</u> 0.100 m ethanol
Value of i = 1 (for non-electrolytes)
So, molal concentration will be =
- <u>Option 3:</u> 0.090 m NaCl
Value of i = 2
So, molal concentration will be =
As, the molal concentration of NaCl is the highest, so its boiling point will be the highest.
Thus, the order of increasing boiling points follows:
