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.

When you divide the mass of a substance by its volume you get its?
That quotient is the object's "density".mass of an object divided by volume = mass per unit volume = density of that object.
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.

We need to know the density of the lotion to calculate the volume. V=M/d
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.

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
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?
density = mass/volume mass = 245-200= 45 grams volume 26 mL = 45g/26ml =1.7 g/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.
