P= 0.87g/mL or 0.87g/cm^3
Mass/Volume = Density
The density of a substance can be found by dividing the mass by the volume, or using the formula below.
The mass of the liquid is 17.4 grams. The volume of the liquid is 20 milliliters. Therefore,
Substitute the values into the formula.
Divide the values.
The density of the liquid is 0.87 grams per milliliter.
Answer : The density of sample of liquid is 1.28 g/mL
Density : It is defined as the mass contained per unit volume.
Formula used :
Mass of sample of liquid = 0.16 kg = 160 g
conversion used : (1 kg = 1000 g)
Volume of sample of liquid = 125 mL
Now put all the given values in the above formula, we get:
Therefore, the density of sample of liquid is 1.28 g/mL
Answer is: D) Some liquid with the higher boiling point will be collected along with the liquid with the lower boiling point.
For example if we have mixture of water and alcohol ethanol, we can separate water and ethanol with distillation (process of heating and cooling).
Ethanol and water have different boiling points (physical property), ethanol has boiling point (78.37°C) and water (100°C).
When the mixture is quickly heated, water contains a lot of ethanol.
The temperature should stay more or less constant.
The answer is0.99 g/mL
The density of a substance can be found by using the formula
From the question
mass of liquid = 3.75 g
volume = 3.8 mL
Substitute the values into the above formula and solve for the density
The density is
We have the final answer as0.99 g/mL
Hope this helps you
The density of the liquid is 0.87 g/ml
Density = 17.4g divides 20ml = 0.87 g/ml (rounded to one significant figure)
The density of the liquid is 1.3 g/mL.
The mass of the liquid is 0.16 kg = 160 g.
The volume of the liquid is 125 mL.
Density = mass/volume = 160 g/125 mL = 1.3 g/mL
d = m/v
In this case the density would be 2kg/10L which works out to 0.2kg/L.
and a volume of 20 ml?...
