Read the volume of the fluid of the graduated cylinder above. Note that each interval is equal to 0.2ml
1 answer:
The volume of the liquid = 8.7 ml
<h3>Further explanation</h3>Graduated cylinder is a laboratory tool used to measure the volume of liquid
Also called a measuring cylinder
Each line (marked line) on this cylinder shows a scale that shows the total volume of water.
The reading is based on a curve of the fluid formed called the meniscus. Read the measurement of the amount of fluid at the bottom of the meniscus (the position of our eyes is parallel to the level of the meniscus and the cylinder is located in a flat (not tilted) place
If we look at the picture (attached), the meniscus is located between the scale / line 8.6 and 8.8(interval 0.2 ml), so the volume of the liquid shows the number 8.7 ml

Answer:
<h3>The answer is 8.29 %</h3>Explanation:
The percentage error of a certain measurement can be found by using the formula
From the question
actual density = 19.30g/L
error = 20.9 - 19.3 = 1.6
We have
We have the final answer as
<h3>8.29 %</h3>Hope this helps you
382.85 Celsius is the temperature does 0.750 moles of an ideal gas occupy a volume of 35.9 L at 114 kPa.
Explanation:
Given data:
number of moles of the gas = 0.75 moles
volume of the gas = 35.9 liters
pressure of the gas = 114 KPa or 1.125 atm
R = 0.0821 latm/moleK
temperature of the gas T = ?
The equation used to calculate temperature from above data is ideal gas law equation.
the equation is :
PV = nRT
T =
Putting the values in the above rewritten equation:
T =
T = 655.9 K
To convert kelvin into celsius, formula used is
K = 273.15+ C
putting the values in the equation
C = 656 - 273.15
= 382.85 Celsius
