What is the difference between balance and graduated cylinder?
A balance is used to measure the mass of an object by comparing it to known weights, while a graduated cylinder is used to measure the volume of a liquid. The balance provides a quantitative measure of mass in grams, while the graduated cylinder provides a quantitative measure of volume in milliliters.
What is the density of a 600 mL liquid sample that weights 450 g?
Because density is d=G/V: 450/600=0,75 g/mL.
How do you move a gas cylinder?
To move a gas cylinder safely, ensure it is securely capped and use a cylinder cart or trolley designed for that purpose. Always make sure the cylinder is upright and secure during transportation to prevent leaks or damage. Use appropriate personal protective equipment and follow all guidelines provided by the gas supplier.
What is the relationship between molecular weight and density in a substance?
The relationship between molecular weight and density in a substance is that generally, substances with higher molecular weights tend to have higher densities. This is because heavier molecules are more tightly packed together, leading to a higher mass per unit volume, which results in a higher density.
Three 10mL samples of urine weigh 10.01g 10.20g and 10.36g respectively Which sample represents normal urine in terms of density?
The density of normal urine is around 1.010 g/mL. Comparing the weights to volumes, the first sample has a density of 1.001 g/mL, the second has a density of 1.020 g/mL, and the third has a density of 1.036 g/mL. Therefore, the second sample with a density of 1.020 g/mL represents normal urine in terms of density.
What is the density of liquid the mass of a graduated cylinder was 28g. 30 ml of liquid poured into a cylinder?
The difference between the weights (grams) of the empty cylinder, and with the liquid gives you the weight of the liquid. Divide that by 30 to get the density of the liquid in g/ml
Do you count weights on both sides when measuring balance?
Yes, weights on both sides are counted when measuring balance.
A cube measuring 2cm on each side weights 5g will it sink or float?
Calculate its volume. Divide mass by volume to get its density. Compare that to the density of water - assuming you want to figure out whether it will float or sink in water.
What weights and measure inspectors do?
Weights and Measures Inspectors test and verify weighting and measuring equipment for trade use.
Is a pound something that is used for measuring culinary units and weights?
yes
What makes an object sink or float?
maybe the density of the objects
How do you measure the mass of an empty graduated cylinder?
The easiest way is to place the graduated cylinder on a scale or balance and measure the weight. You would then calculate from the weight (a force measured in kg, usually) to determine the mass.
What is the Buoyancy calculation?
buoyant force can be expressed as: F(b) = W(air) - W(liquid) = d * g * v where d is the density of the liquid, g is the acceleration of gravity and v is the volume of the immersed object (or the immersed part of the body if it floats). In this experiment the pan balances will compare masses in grams rather than weights. Since W=mg, the apparent change in mass when submerged is m - m(apparent) = d(liquid) * v
What is the difference between balance and graduated cylinder?
A balance is used to measure the mass of an object by comparing it to known weights, while a graduated cylinder is used to measure the volume of a liquid. The balance provides a quantitative measure of mass in grams, while the graduated cylinder provides a quantitative measure of volume in milliliters.
How is the mass of an object measured with a scale a balance a graduated cylinder or a thermometer?
The mass of an object is typically measured using a scale by comparing it with known weights. A balance also functions by comparing the mass of the object with known masses on the opposite side. A graduated cylinder is used for measuring volume, not mass. A thermometer measures temperature, not mass.
Why do some weights feel heavier than others?
Some weights feel heavier than others because of their mass and density. The more mass and density a weight has, the more force is required to lift it, making it feel heavier.
Two different objects are completely immersed in water and undergo same loss in weightis it necessary that the weights of these objects in air be also the same?
Ooooh, tricky question. You said that each object "lost" the same amount of weight in water, and that means that the two objects were the same size (i.e., they displaced the same amount of water when submersed, therefore the same weight loss), but it does not mean they weighed the same to start with. Regardless of their intitial weights, they will lose an amount equal to the weight of water they displace. So, no, the two objects do not necessarily weigh the same in air, but they might. There is no information here to tell you whether they do or do not. Ray
