You can use the density of the object.
Density is the mass per unit volume of a substance. Density = mass / volume. Rearrange it to solve for mass. Mass = density x volume.
You can find the density of the substance from a table of densities.
Or depending on what you know about the substance:-
moles = volume (dm3) x concentration (moldm-3)
moles = mass/Mr
Mr = molecular weight
100cm3 = 0.1dm3
If you know the volume, concentration and the Mr then mass can be solved by calculating the moles of the substance and multiplying by Mr.

How do i calculate the mass of a hydrometer if the density of the liquid is 0.80gcm and depth is 7.5cm?
To calculate the mass of the hydrometer, you need the volume of the liquid displaced by the hydrometer. Since the density of the liquid is 0.80 g/cm³ and the depth is 7.5 cm, the volume of the liquid displaced would be 7.5 cm³. You can then calculate the mass by multiplying the volume of liquid displaced by the density of the liquid.
How to find the density of liquids?
To find the density of a liquid, you need to measure its mass and volume. The formula for density is density mass/volume. First, measure the mass of the liquid using a scale. Then, measure the volume of the liquid using a graduated cylinder. Finally, divide the mass by the volume to calculate the density of the liquid.
What equipment do you need to find mass in liquid?
To find mass in a liquid, you will need a balance or scale, a container to hold the liquid, and a pipette or graduated cylinder to accurately measure the volume of the liquid. You can then use the formula density = mass/volume to calculate the mass of the liquid.
A 30ml sample of an unknown liquid has a mass off 100g what is the density?
Density is calculated by dividing the mass of a substance by its volume. In this case, the density of the unknown liquid is 100 g / 30 ml = 3.33 g/ml.
What is the density of a rock that has a mass of 56 grams?
The density of the rock is calculated by dividing its mass (56 grams) by its volume. If the volume is unknown, then the density cannot be determined. Density is the mass per unit volume of a substance, so both mass and volume need to be known to calculate it.
How can you find the density of an unknown liquid?
To find the density of an unknown liquid, you can measure its mass using a scale and then measure its volume by using a graduated cylinder or displacement method. Divide the mass by the volume to calculate the density of the liquid.
Is the volume of the unknown mass needed to calculate the mass of calcium oxide?
No. you will know the volume of the unknown mass after you calculate the mass of ca0
Explain how can you find the density of an unknown liquid if you have all of the laboratory equipment you need?
To find the density of an unknown liquid, you would first measure the mass of a known volume of the liquid using a balance. Then, you would measure the volume of the liquid using a graduated cylinder. Finally, divide the mass by the volume to calculate the density of the unknown liquid.
What procedures would you follow if you wanted to calculate the density of an unknown substance?
To calculate the density of an unknown substance, first measure its mass using a balance. Then, determine its volume by either measuring its dimensions and calculating the volume or using displacement method in a liquid. Finally, divide the mass by the volume to calculate the density of the unknown substance.
Explain how you would find the density of an unknown liquid if you have all the laboratory equipment that you need?
To find the density of an unknown liquid, you would weigh a known volume of the liquid using a balance to determine its mass. Then, you would divide the mass by the volume to calculate the density. Make sure to use the proper units for mass (grams) and volume (milliliters or cubic centimeters) in your calculation.
What is the density of an unknown liquid with a mass of 30.6 g and a volume of 53.3 ml?
The density is mass/volume = 30.6g/53.3ml = 0.5741 grams per millilitre.
How can we calculate the density of a irregular solid or a liquid?
You can dip the irregular solid in a water or other suitable liquid. This is how, you can measure the volume of the solid. The mass can be measured by weighing scale. Mass/volume = density. It is easy to measure the mass and volume of the liquid. First measure the mass the container. Then add the liquid to it. You will get the mass of the liquid. Then measure the volume of the liquid. Use the above formula to calculate the density of the liquid.
How do i calculate the mass of a hydrometer if the density of the liquid is 0.80gcm and depth is 7.5cm?
To calculate the mass of the hydrometer, you need the volume of the liquid displaced by the hydrometer. Since the density of the liquid is 0.80 g/cm³ and the depth is 7.5 cm, the volume of the liquid displaced would be 7.5 cm³. You can then calculate the mass by multiplying the volume of liquid displaced by the density of the liquid.
How would you find the density of an unknown liquid if you have all of the laboratory equipment that you need?
This depends on the nature and form of the sample:- for a solid with a regulate shape weight the sample and calculate the volume from the dimensions; density is the ratio between mass and volume. You can measure the volume of great sample by water displacement.- for other solids use a pycnometer- for liquids use a densimeter (simple or electronic)etc.
Write a step-by-step process for finding the density of an unknown liquid List the laboratory equipment needed for each step?
To find the density of an unknown liquid, first, gather the necessary equipment: a graduated cylinder, a balance, and a thermometer. Begin by measuring a specific volume of the liquid using the graduated cylinder, noting the volume accurately. Next, weigh the graduated cylinder filled with the liquid on the balance to determine its mass. Finally, calculate the density by dividing the mass of the liquid by the volume measured (Density = Mass/Volume).
What is the procedure to calculate the density of an unknown substance?
divide mass and volume(:
What is the relationship between the volume of a liquid and its mass?
The mass of a liquid and the volume of it are not related, they have no bearing on one another. The mass and volume can change independently, in theory. They are related by the equation to calculate density. Density=Mass/Volume
