Answer:
1.59 g/mL
Explanation:
Mass of CCl₄ = mass of flask and CCl₄ − mass of empty flask
m = 703.55 g − 345.8 g
m = 357.75 g
Density = mass / volume
d = 357.75 g / 225 mL
d = 1.59 g/mL
Answer:
Density is the relationship between mass and volume.
D = M / V
Based on the ideal gas equation, the pressure (P), volume (V) and temperature (T) corresponding to n moles of an ideal gas are related as:
PV = nRT
where R = gas constant
Under conditions of constant pressure and number of moles:
The volume is directly proportional to the pressure. Therefore, as the temperature drops the volume will also decrease.
V α T
This is also known as the Charles Law.
Based on the given values above, in order for us to get the answer, we need to convert the units first. So in 1 kilogram, there is 1,000,000 micrograms. In this case, 1.6 kilograms is 1,600,000 micrograms. For the week to seconds, 1 week is equivalent to 604,800 seconds. Therefore, 1,600,000 micrograms/604,800 seconds. So we are going to simplify this. So it would be 2.65<span>µg/s. Hope this answers your question.</span>
