A small toy has a volume of 20 cm and a mass of 45g what is the density of the toy?
No way exists to answer your question. 20 cm is a unit of length. It is not a unit of volume. Knowing that your toy is 20 cm long and has a weight of 45 g does not provide enough information to give the density of the toy. Take your toy. Put it into a large beaker. Cover the toy with water. Put a mark on the side of the beaker at the waterline. Remove your toy. Put a mark at the top of the water line. Fill a graduated cylinder to the top line. Now, slowly pour water into the beaker until you raise the level of the water to the top line. Write down how much water you poured into the beaker. Now take that amount in ml and divide it into the number of g. If it is 22.5 ml and 45g your density is 2.
What else can I help you with?
When you divide the mass of a substance by its volume you get its?
Density. Density is a physical property that quantifies how much mass is present in a given volume of a substance. It is typically measured in units such as grams per cubic centimeter (g/cm^3) or kilograms per liter (kg/L).
How many ml in 45g face cream?
The volume of 45g of face cream can vary depending on its density. However, a rough estimation would be approximately 45mL, as 1g of most creams is roughly equivalent to 1mL in volume. It is best to check the packaging for specific information on the product.
How do you calculate mass of a liquid when volume is unknown?
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.
Which is bigger 45 grams or 1.5 kilograms?
It is 1.5 kilograms because if you change the 45g to kilos you would get 0.040kg and you change 1.5kg to simple kg. you get 1.500 kg. Therefore, the answer is 1.5 kilograms is larger.
How many oz in 45 grams?
Set up the equation as follows: gr 45 X 60mg/gr1 X 1g/1000mg = 2700/1000 = 2.7 g
What is the density of and object with a volume of 238cm3 and a mass of 45g?
The object's density is about 0.19 g/cm3
If you have a rock with a volume of 15cm3 and a mass of 45g What is its density?
The rock's density is 3 g/cm3
If a graduated cylinder has a mass of 200g when 26ml of a liquid is added and it rises to 245 g What is the density of the liquid?
The increase in mass is 45g (245g - 200g) due to the added liquid. This corresponds to a volume of 26ml because 1g/ml is the density of water (and marketed) liquids. Therefore, the density of the liquid is 45g / 26ml = 1.73 g/ml.
What is the density of a substance with a mass of 45.0g and a volume of 26.4ml?
Density = Mass / Volume Density = 45grams/5ml = 9g/ml
A sample of fluid has volume of 15 ml and a mass of 45 g. What is the density of the fluid?
Density = Mass/Volume D = M/V D = 45g/15ml D = 3g/ml
What is more denser 30ml solution with mass of 45g or 40 ml solution with mass of 50g?
A 30ml solution with a mass of 45g has a density of 45/30 or 1.5 g/ml, while a 40ml solution with a mass of 50g has a density of 50/40, or 1.25 g/ml. The 30ml solution with a mass of 45g has a higher density.
When you divide the mass of a substance by its volume you get its?
Density. Density is a physical property that quantifies how much mass is present in a given volume of a substance. It is typically measured in units such as grams per cubic centimeter (g/cm^3) or kilograms per liter (kg/L).
Is 45g in 50mL?
No, 45g is not equal to 50mL. Grams and milliliters are different units of measurement. Grams measure mass or weight, while milliliters measure volume. To determine if 45g is equal to 50mL, you would need to know the density of the substance being measured.
What is the density of a perfect rectangle that has a mass of 45g 1cm 3cm 5cm?
15X3cmX1cmX3cmX5cm=61
1 mass 45g and volume5cm3?
The density of the object is 9 g/cm^3 (45 g / 5 cm^3). Density is a measure of how much mass is contained in a given volume, so it describes how compact the molecules are within the object. With this information, you can calculate the mass or volume of the object given the other value.
How many ml in 45g face cream?
The volume of 45g of face cream can vary depending on its density. However, a rough estimation would be approximately 45mL, as 1g of most creams is roughly equivalent to 1mL in volume. It is best to check the packaging for specific information on the product.
