The question requires us to use the dilution formula , where
and
are the stock concentration and volume respectively, then
and
are the dilute concentration and volume respectively.
a. = 1.5 M KCI,
=0.20M KCl,
=250ml KCl
b.
To prepare the solution 33.3ml of 1.5M KCl is diluted to a total final volume of 250ml.
Answer:
Explanation:
The Celsius and Kelvin scales are used to measure the temperature of matter. Their scales and unit differences are the same (1 K increase = 1 °C increase), but they have different starting points.
So, the conversion is quite simple and only requires addition because of the different starting points. The formula is:
The boiling point of liquid nitrogen is -195.8 °C. We can substitute this value into the formula.
The boiling point of liquid nitrogen is 77.35 Kelvin.
