FAQs

When using a properly stabilized balance How should you ensure? ›

When using a properly stabilized balance, how should you ensure that you get the most accurate mass reading possible? Measure the mass of the sample at room temp. Close the side shields on the balance during reading.

what was the first step of using the balance before adding anything to a weighing dish? tare the balance with the weighing dish and the balance is closed.

What should you do if you are using a balance that has persistent fluctuations in mass? Switch to using another balance. Record all the fluctuations as your mass reading. Contact your TA or instructor to adjust the balance.

When you use a balance to weigh a reagent, you should weigh onto: a folded weighing paper or weighing boat. When pouring a solution from a reagent bottle into a beaker, the beaker should be: placed on a bench.

Step 1: Before each measurement, make sure the scale reads zero.

Close to Side shields on the balance during reading is correct answer because side shields prevent entry of air or moisture inside.

Step 1: Identify the mass of the solute. Step 2: Identify the volume of solution. Step 3: Divide the mass of the solute by the volume of solution to find the mass concentration of the solution.

Weighing a solid object directly on the balance

If the object you need to weigh is a solid object, you can weigh it directly on the pan. Be sure the balance is zeroed. Open the chamber doors, carefully place the object on the balance pan, close the doors, and read the mass of your object.

The flow of food begins with purchasing, then receiving and storing food. Once food becomes unsafe at one of these steps, it cannot be saved, so food must be purchased from reliable sources, received safely, and stored properly.

Which type of balance should you use if you need to accurately weigh a mass of approximately 1g? ›

Balance scales are commonly referred to as a laboratory balances or analytical balances where the resolution of the balance is generally between 0.001mg to 1g. This makes a balance scale ideal for situations where the mass of the object is extremely small and precision is essential.

The glassware (i.e. filter flask) should not have any cracks on the sides or the bottom. It is also imperative that the filter flask and the vacuum trap are clamped securely, so that they do not move during the filtration.

Only glass, ceramic, metal or plastic objects and containers should be placed in direct contact with the balance pan. Do not handle objects to be weighed with bare hands. Moisture, grease and dirt on you fingers will affect the weight of the objects. To be weighed accurately, all objects must be at room temperature.

What are the best practices while sharing a lab balance with other students? Alert your TA or instructor about any issues with the balance. Brush off any chemical dust around the balance after each use. An instrument for determining the density of a liquid relative to that of water.

do not keep the weight balanced in the windy areas as it can affect the readings. Do not weigh a solid directly, use a paper for weighing any solid. do not weigh hot or cold objects on the balance as the readings will be altered due to air buoyancy. Do not open the balance unless it will alter the readings.

You should always use the balance to its full precision, and then tidy up the significant figures as your calculations develop. Use the same balance. It is critical to always use the same balance especially if calculations require more than one mass measurement, as each device might be calibrated slightly differently.

An important thing to remember in maintaining your electrode include your sensing bulb and reference junction to be immersed in a buffer solution at all times.
