What container should be used in weighing sticky and adhesive substance?
Electronic single-pan balances with digital readouts are now favoured over mechanical types and are common in most laboratories. There are essentially two types of balance: General-purpose balances which weigh to the nearest 0.01 g with a capacity of about 300 g. Chemicals may be dispensed for weighing, into a suitable weighing container, directly onto these balances. Analytical four-figure balances for quantitative work, which weigh to the nearest 0.0001 g (0.1 mg) and have a maximum capacity of about 100 g. Chemicals must not be transferred onto the balance at any time and analytical balances must only be used for weighing by difference. Both types are illustrated in Fig. 4.3 and you should familiarize yourself with their operation before use.
Why the sodium hydroxide is weighing in a weighing bottle and not on a piece of filter paper?
Because sodium hydroxide is deliquescence and will absorb carbon dioxide from the air if exposed to it, therefore the weighing is performed in weighing bottles and not in the open, like on a piece of paper.
The simplest type of balance for weighing is the?
a balance
A 15.7g sample of sodium carbonate is added to a solution of acetic acid weighing 18.9 g and after reaction weighing 26.3g what is mass of carbon dioxide?
8.7g
How weighing by difference eliminates systematic balance error in analysis of an unknown acetic acid solution experime?
Weighing by difference can reduce, but not eliminate, systemic errors in an experiment because systemic errors do not arise simply from errors in measurement, but from a variety of sources. Weighing by differences is still advised whenever possible.
How do you find the mass of an animal?
Basically by weighing it. Although mass is not the same as weight, if you know the weight and the gravity, you can calculate the mass.Basically by weighing it.

What is the volume of the human stomach in milliliters?
It really depends on the person, for example an obese person weighing 350 pounds or more is more likely to have a larger capacity than a person weighing 150 pounds

How do you calculate urine output from weighing wet diapers?
A conventional baby scale can be used to calculate urine output. Weight the diaper before putting it on your baby, and then again when it is wet.
Calculate the kinetic energy in joules of an automobile weighing 2135 lb and traveling at 55 mph?
The kinetic energy in joules of an automobile weighing 2135 lb and traveling at 55 mph is 2.9 x 105.
How do you calculate percentage error on weighing scales?
do the margin of error on the weighing scales (e.g. 0.05) then divide that by the measurement taken (e.g. 3.5g) then times that by 100 so 0.05/3.5 x 100 = 1.4%
What is the body surface area for a child weighing 7.5 pounds?
You need both height and weight to calculate body surface area.
What are stuff that represent weight?
Weighing Machines are used to calculate and display weight of items. Weight is usually displayed in Kilograms (Kgs) or Pounds (lbs)
How can you calculate the volume of an object with only the knowledge of the density?
You cannot calculate the volume of an object using only the density; you must also calculate the mass.You can calculate the mass by simply weighing the object.Density = Mass / VolumeTherefore Volume = Mass/Density.If you cannot be bothered to calculate the mass, simply measure the object. Multiply the length, times the width, times the height and you have the volume.
How do you calculate grammes per square meter?
This is done by measuring a sample of the item and weighing it. It is easiest if the sample measures 1 square metre, or an exact multiple of it.
