How do you calculate the volume of a drop of water? I want to use Volume = mass/density. Density of Water = 1g/cm^3 How much water do I measure to calculate an approximate mass and how?
Why would you want an approximate mass? If that's the route you want to take, you can weigh the drop and get an exact mass. Don't forget your density equation brings with it certain assumptions.
Water is a special case (pure water that is): its mass in grams is equal to its volume in cubic centimeters\[\frac{ xg }{ \frac{ 1g }{ 1cm ^{3} } }=x cm ^{3}\]Units cancel out like numbers
How do I measure the mass? Should I use more than one drop of water? If so, how do I calculate one drop of water from a multitude of drops? Divide by the amount of drops?
Usually you have a scale to measure the mass...
Yes. I will have a scale, however, will I need to use more than one drop on the scale? Or just drop one drop onto the scale and don't use extra water ?
Well, that depends on how well-calibrated the scale is; if I were you, and I had to measure the mass of a "drop" of water, I'd "drop" drops until the mass showed up and then divide the given mass by the number of drops I used. Not the surest of methods, but what's a drop anyway?
I will be using an electronic scale, just so you know. :)
I wish I could help you more, but I'm not really able to tell you what I don't know. Just remember: with water, volume is mass, so to speak (cf. one of my former entries), so if you can measure volume instead you can dispense with the scale
