A volume of water delivered using a buret has a mass of 2.67 g. What was the final volume reading on the buret if the inital volume reading was 0.30 ml? [assume the density of water is 1.00g/mL]
Final Volume=Initial Volume + Volume of water delivered
Use the density of water and solve for volume:
Density=mass/volume
So,
Volume=mass/density
Volume of water delivered=2.67g/1.00g/mL
Grams cancel out and you are left with volume (mL)
Volume of water delivered=2.67mL
Final Volume=0.30mL+2.67mL
To find the final volume reading on the buret, we need to determine the change in volume of the water delivered.
1. Calculate the mass of water delivered:
Mass of water = Mass of water and buret - Mass of buret
Mass of water = 2.67 g - (mass of the buret)
Note: We subtract the mass of the buret to get just the mass of the water.
2. Convert the mass of water to volume using the density of water:
Volume of water = Mass of water / Density of water
Volume of water = Mass of water / 1.00 g/mL
3. Determine the change in volume:
Change in volume = Volume of water - Initial volume reading
4. Calculate the final volume reading:
Final volume reading = Initial volume reading + Change in volume
Let's plug in the given values and calculate the final volume reading:
Mass of water and buret = 2.67 g
Initial volume reading = 0.30 mL
Density of water = 1.00 g/mL
1. Calculate the mass of water:
Mass of water = 2.67 g - (mass of the buret)
If the mass of the buret is not provided in the question, we cannot determine the mass of water accurately. We need the mass of the empty buret to subtract it from the total mass of water and buret.
If you have the mass of the buret, substitute it into the equation to find the mass of water. For example, if the mass of the buret is 0.10 g:
Mass of water = 2.67 g - 0.10 g = 2.57 g
2. Convert the mass of water to volume:
Volume of water = Mass of water / Density of water
Volume of water = 2.57 g / 1.00 g/mL = 2.57 mL
3. Determine the change in volume:
Change in volume = Volume of water - Initial volume reading
Change in volume = 2.57 mL - 0.30 mL = 2.27 mL
4. Calculate the final volume reading:
Final volume reading = Initial volume reading + Change in volume
Final volume reading = 0.30 mL + 2.27 mL = 2.57 mL
Therefore, the final volume reading on the buret is 2.57 mL.
