What is a formula for measuring the mass of a liquid such as water?

Question

I need to know another way (besides using a three-beam scale) to measure the mass of a glass of water for a science project I am doing.

Answer 1

If we consider the volume of water is known.(If not known then use graduated cylinder and find the volume)
Mass of water can be calculated using following formula:

Density(ρ)=mass(m)/volume(V) , where
ρ is the object's density (measured in kilograms per cubic meter)
m is the object's total mass (measured in kilograms)
V is the object's total volume (measured in cubic meters)
(Temp (°C)/ Density (g/cm3)
30/ 0.9957
20 /0.9982
10 /0.9997
0 /0.9998
−10/ 0.9982
−20 /0.9935
−30/ 0.9839 )

Answer 2

The density of wate is 1 gm/ml or 1 kg/l

We know, Mass=density x volume

so if you know the volume of the water contained in the glass (a measuring glass has volume information) then you can calculate the mass.

Suppose, you have 250 ml of water

then mass= 1 x 250 = 250 grams.

So, the mass of the water is 250 grams!!

Answer 3

Density (symbol: ρ - Greek: rho) is a measure of mass per volume. The average density of an object equals its total mass divided by its total volume. An object made from a comparatively dense material (such as iron) will have less volume than an object of equal mass made from some less dense substance (such as water). The SI unit of density is the kilogram per cubic metre (kg/m3)

p = m/v


where

ρ is the object's density (measured in kilograms per cubic meter)
m is the object's total mass (measured in kilograms)
V is the object's total volume (measured in cubic meters)

Answer 4

The mass/volume ratio of the metric scale is based on the density of water. That is one liter of pure water is equal of one kilogram, and one milliliter (or cubic centimeter) of water is equal to one gram.

Of course, any non-distilled water you have will vary somewhat from that standard because of minerals and other impurities in the water, but this figure should be close enough for most experiments.

Answer 5

Check the amount of water using a calibrated container and check the water temperature.

Answer 6

ml or Litres

Answer 7

mass = molar mass / moles

Answer 8

ounces
