volume is not equal to mass. a gas will expand or contract depending on the temperature and pressure of its surroundings. the same amount of water is there it's just more spread out.

the 30L water vapor sample is a gas gases exert pressure on their surroundings thus taking on the shape of their containers the gas is under 1 ATM of pressure so it exerts pressure in return and the volume becomes 30L when the presures are equal if the temperature were to decrease to room temperature, the water vapor would condense to a liquid and the volume would decrease liquids have a volume but no definite shape while gases have neither a definite volume or shape

18/18 x Avagadros number = 6.023 x 1023 molecules of water making the assumption that 1ml of water has 1 g mass. There are 8 electrons in oxygen and 1 from each hydrogen so a water molecule has 10 electrons so 6.023 x 1023 x 10 = 6.023 x 1024 electrons *********** because 18ml of H2O = 1 mole of H2O so. 18ml contains 6.023X1023 atoms and water has 10 electrons so, 10 e x 6.023 x 1023 = 6.023 x 1024

No. 49.33L describes measurements down to hundredths of a liter. 18ml describes measurements down to thousandths.

0.6 ounce

It would take up the volume of the container it was in. If you want to find the volume of the water vapor at a certain pressure, you can use the Idea Gas Law: PV = nRT, where P is pressure in Atm, V is volume in L, n is the number of moles (18 mL of water is about 1 mole), R is the ideal gas constant(0.08206 L*Atm/mol*K), and T is the temperature in Kelvin (temperature in Celsius plus 273.16).

Around 18ml

18ml

18mL is 3.65 US teaspoons.

1.5*12 is 18ml.

It depends on the absorbency rating, the most a tampon can absorb is 18ml

18mL equals 0.18dL (there are 100mL per deciliter).

Obviously 15 - 18ml per gram approx.

Milliliters can't be converted to grams. Milliliters measure volume, while grams measure mass.

4750ml - 18ml = 4732ml.......

18 ml equals0.608652409 US fluid ounces

It's not a matter of size, but of absorbency - the most absorbent tampon is an Ultra absorbency, regardless of brand all Ultra absorbency tampons hold 18ml maximum. Size-wise options like sponge tampons can be bigger than commercial tampons.

One teaspoon is about 5ml. So 18ml would be around/just under 4 teaspoons. Check the related link I have provided below. It gives you a detailed chart of teaspoon measurements converted to ml.

Depends. It sounds like a vague question. Say you wanted to know how mLs are in 1mol of pure water @ 25c. 1mol of water is 18g. The density of water is 1g/1ml. So 1mol of water is 18mL. So convert the amount of moles into grams. And times the amount of grams by the density. M x D = mL Or if you want to know how many mLs are in 2mols of 0.5mol/L solution. Which is is 4000mL btw. You would divide the amount in moles by the molarity of the solution. N / C = mL Hope I have been somewhat helpful :)

A unit of alcohol is the amount of alcohol that is in one (12-oz or 16-oz) beer, one (6-oz) glass of wine, or one shot of hard liquor. 12 ounces (approx. 375ml) of 5% beer will contain about 18ml of pure alcohol; that is approximately one unit.

An illustrative way to solve this problem.Density water:1 gram/ml = X grams/1 ml= 18 grams water================now, find amount atoms and from experience one sees that this will be Avogadro's number of atoms. 6.022 X 1023 atoms.total atoms water * molar ratio to get atoms hydrogen. Two hydrogen atoms in compound.2 * 6.022 X 1023 = 1.204 X 1024 atoms hydrogen, which means1.204 X 1024 electrons hydrogen=======================================================

1.0 M = x mol HCl /.018 L of solution x = .018 mol HCl Since HCl --> H+ and Cl- in a 1 to 1 to 1 ratio, then you will also have .018 mol of H+ in solution.

It's not dangerous, it's just not possible.Tampons expand when wet so is they had been soaked in alcohol you'd not be able to insert them correctly, even if you did at most it may cause irritation and vaginal infections...just in case you're wondering this won't get you drunk, even an ultra absorbency tampon can only absorb 18ml at most, which isn't even as much as a single shot.

3 weeks = 7days x 3 weeks = 21 days. 6cc tid means 6ml thrice a day so 6cc x 3 = 18 cc a day (i.e. 18 ml /day) so , 18ml x 21 days = 378 ml i.e. you require 378 ml medication for 3 weeks.

This is a little indeterminate because of the variables, warming of the oceans alone will cause the water in them to expand and therefore a rise in levels will result 'without' any extra water. But more of the world's ice will melt and it will abstract heat not only from the air but from the sea too, remember roughly a third of an iceberg is under water and water expands when it freezes so contraction results when ice melts adding to the ambiguity. Higher global temperatures will cause more evaporation of the sea so more of the earths water will be in the form of water vapour in the atmosphere. This will also result in the air being slightly heavier so more atmospheric pressure would be exerted on surface of the sea. So all in all it is impossible to calculate a rise in sea level as there are so many variables, even the top scientists are arguing about it. But if you just literally wanted a plain answer, the sea covers roughly two thirds of the surface of the planet: Earths surface area ~ 183,589,372 mile square, Divided by 2/3 ~ 122,392,914 miles square of sea surface area. That's 4.91x10^17 inches square or 491,000,000,000,000,000 inches square. It would take 1 cubic inch in volume to raise the sea level 1 inch in 1 square inch of surface area. 1 cubic inch = 16.39 cubic cm 1 cubic cm = 1ml So 16.39 x 4.91x10^17 = 8.04749x10^18ml 8.04749x10^18 divided by 1,000 = 8.04749x10^15 Litres or 8,047,490,000,000,000 Litres or 8,047,490,000,000 Tonnes 0r 1,770,447,800,000 gallons (UK) These are rough calculations based on a sphere with a circumference of 24,000 miles. Anyone wishing to be pedantic and argue my sums, should really get a life as should I come to think of it :/
