You can do it in 5 steps.
Against the stone (S) weigh 1kg of Rice (1R)
Move 1R to the same side as S and, against S+1R, weight 2R
Move 2R to the same side as S and, against S+3R, weight 4R
Move 4R to the same side as S and, against S+7R, weight 8R
Move 8R to the same side as S and, against S+15R, weight 16R
15R + 16R = 31R.

How do you use a balance scale?
A balance scale uses a weighing plate and a counter. It typically does not matter which plate is used for which purpose. Begin by placing the item to be weighed on one plate. Place the calibrated counter weights on the opposite plate, beginning with smaller weights, and continue until the item being weighed begins to rise. As the two plate reach the same level, the scale balances, and you have determined the weight of your item.
What is the device comparing the mass of an object to a known mass?
The device used for comparing the mass of an object to a known mass is a double pan balance, or a balance scale. This is a type of weighing scale where you put weights on one pan and the substance you are weighing on the other.
When calculating Tons Per Hour being conveyed on a conveyor belt by weighing samples is there a recommended cut length for each sample set?
The answer to the question depends on the weights of each item going down the conveyor.
How do i know if i used 2.6oz of 6.4 oz if i cant see in the bottle?
If you cannot see inside the bottle you can measure the amount of product you used by using a digital kitchen scale. Start by weighing the bottle before use and noting the weight. After using the product weigh the bottle again and subtract the original weight from the new weight. The difference between the two weights is the amount of product you used. For example if the bottle weighed 6.4 oz before use and 4.8 oz after use the difference is 1.6 oz meaning you used 2.6 oz of product.

How to use the set of weights in the physics laboratory?
If the weights are an intact set then one can weigh, with considerable precision, any amount by placing the object to be weighed on one pan of the balance scales and then placing one or more weights on the other side, in increasing magnitudes until the pans balance. It may be necessary to add one or more weights to the side containing the object being weighed to achieve stability. Then by subtracting the weights on that side from the weights on the other, one can calculate the weight of the object. When weighing liquids or large quantities of loose material, remember to weigh the empty container first and to subtract that value at the end of th weighing, to get the weight of what is contained.

What is the instrument used to measure heavy masses?
How heavy is heavy. Would you call a car heavy? would you call a bag of Potatoes heavy? They both are I suppose . Vehicles of all weights are weighed on a public Weigh-bridge. They can weigh very heavy loads up to about 100 Tonne, and are usually owned by local Councils. Objects more than about 10 Kilogram are usually weighed on a portable Weighing Platform. Example: Airports, Scrap Metal Buyers, Farmers, etc. use Weighing Platforms which are about 1Metre square, for weights in the approximate range of 5 to 500 Kilogram. Bathroom Scales can cope with up to about 150 Kg and are useful for weighing objects other than humans. Example: domestic luggage.

What is the difference between a balance and a scale?
A balance has two pans, you put measured weights in one and the item you are weighing in the other and when the balance is level you sum the known weights to get the unknown's weight. A scale is an instrument with a readout (digital or analog) from which you read the weight of an object places on (in) the weighing surface/dish.
