What is the percent by volume of 25 ml of methanol in 75 ml of water?
With 25ml methanol and 75ml water, there is 100ml in total. So there is 25/100 = 25% by volume methanol.
How do you find the density of methanol?
To find the density of methanol, you would need to divide the mass of a given volume of methanol by its volume. The formula for density is density = mass/volume. The density of methanol at room temperature (20°C) is approximately 0.7918 g/cm³.
How Does a cup full of methanol and a pool full of methanol have the same mass?
A cup full of methanol and a pool full of methanol can have the same mass if the volume of methanol in the cup is equal to the volume of methanol in the pool. Mass is a property that depends on the amount of substance, which is determined by both the volume and the density of the material. If the cup and pool contain equal volumes of methanol, they will have the same mass, regardless of their sizes. However, in practical terms, a cup and a pool typically do not contain equal volumes of methanol.
Why does one need to fix cells with methanol?
Cells are fixed with methanol to preserve their structure and prevent degradation. Methanol helps to maintain the integrity of the cells for further analysis and study.
Is water heavier than methanol?
No, water is heavier than methanol. Water has a higher density compared to methanol, which means that for the same volume, water will weigh more than methanol.
Do Liquids have a fixed but do not have a fixed?
No, liquids do not have a fixed volume - their volume is that of the container
Has no fixed volume or shape?
A gas has no fixed volume or shape.
What is the final percent concentration of the solution when 600 ml of 100 percent methanol added to 4400 ml of water?
The final percent concentration of the solution would be approximately 12.0% methanol. This is calculated by dividing the volume of methanol by the total volume of the solution (600 ml / 5000 ml) and then multiplying by 100 to get the percentage.
What has a volume but not a fixed shape?
A solid has a fixed volume and does not change shape.
How a liquid and a solid different?
A solid has a fixed volume and form. A liquid has a fixed volume but has the form of a container. A gas has not a fixed volume or form.
If the density of Methanol is 0.793 Kg L-1 what is the volume needed for making 2.5 L of its 0.25 M solution?
methanol density is 0.739kg/L mass of methanol is =739g molarity of methanol is = 793*1000/(32.043*1000) that is (M1)=24.75mol/L V1=(M2*V2)/M1 V1 = 2.5*0.25/24.75 V1 = 0.25L so, 0.25L volume needed for making 2.5L of methanol 0.25Msolution
What is the percent volume of 25 mL of methanol in 75 mL of water?
25%
