A volume of water delivered using a buret has a mass of 5.15 g. What was the final volume reading on the buret if the inital volume reading was 0.70 ml?
[assume the density of water is 1.00g/mL]
If the mass is 5.15g and the density is 1.00 g/mL, then the volume must be 5.15 mL. If the buret started at 0.70 then 0.70+5.15 must be the new reading. You know that because the new volume - 0.70 must equal 5.15.
To find the final volume reading on the buret, we need to first calculate the mass of the water that was delivered.
Step 1: Calculate the mass of water delivered
Given: The mass of water delivered is 5.15 g
Step 2: Calculate the volume of water delivered
We can determine the volume of water delivered using the density of water, which is given as 1.00 g/mL.
Density = Mass / Volume
Rearranging the equation, Volume = Mass / Density
Volume = 5.15 g / 1.00 g/mL
Volume = 5.15 mL
Step 3: Determine the final volume reading
To find the final volume reading, we need to add the volume of water delivered to the initial volume reading.
Final volume = Initial volume + Volume delivered
Initial volume = 0.70 mL (given)
Volume delivered = 5.15 mL (calculated in Step 2)
Final volume = 0.70 mL + 5.15 mL
Final volume = 5.85 mL
Therefore, the final volume reading on the buret is 5.85 mL.
