Question

4. A mass of small droplets of water.​

Answer 1

Answer:

In other words, 1 millilitre of water has a mass of 1 gram. One drop of water is 0.05 mL of water, so its mass would be 0.05 grams. One mole of water is 18.016 grams, so in 0.05 grams, in one drop, the number of moles is: moles of water in one drop = 0.05 grams x (1 mole/18.016 grams

Explanation:

mark me as the brainlest please

Answer 2

Answer:

m=pv

Explanation:

Assuming that a drop of water is 1 mL and it’s in liquid form the equation is fairly simple.

M = pV

Where M is mass, p is density and V is volume .

The molecular density of water is .99988396 grams per cubic milliliter at 0 degrees Celsius. For the sake of simplicity we can round up to 1 gram.

Mass = (1)1 = 1 gram /ml

Keep in mind that the hotter or colder your water the density will vary.

Hope that helps!
