It is 0.87 g/mL.
The density of the object is calculated by dividing its mass by its volume. In this case, the density would be 4000g / 20ml = 200 g/ml.
The density of the unknown metal is 7.9 g/mL. This is calculated by dividing the mass (158g) by the volume (20mL).
You cannot directly associate weight and volume. You firstly need to know the shape and other dimensions in order to find the volume. Then you need to apply the density of the material, i.e. what it weighs per volume.
The volume of the three coins is 33 ml. This can be calculated by subtracting the initial volume of water (20 ml) from the final volume of water (53 ml), which gives the volume occupied by the three coins.
It is 0.87 g/mL.
The density of the object is calculated by dividing its mass by its volume. In this case, the density would be 4000g / 20ml = 200 g/ml.
To determine the density of a substance, you need to divide the mass by the volume. In this case, the density would be 40 grams / 20mL = 2 grams per milliliter (g/mL). Density is a physical property that describes the amount of mass per unit volume of a substance.
density = mass / volume = 52 / 20 = 2.5 g cm-3 Note the units used. Density is commonly measured in grams per cubic centimeter. However using millilitres does not affect the answer since 1 ml = 1 cm3
This well known formula should lead you on your path: Density (grams/ml) = mass/volume
A 10 ML of liquid can't fill a 20 ML container because although liquids do not have a definite shape they have a definite volume.
The density of the unknown metal is 7.9 g/mL. This is calculated by dividing the mass (158g) by the volume (20mL).
No, changing containers will not change the liquid volume.
You cannot directly associate weight and volume. You firstly need to know the shape and other dimensions in order to find the volume. Then you need to apply the density of the material, i.e. what it weighs per volume.
20ml equals 4 tsp of liquid.
this is valid for water only (or any fluid with same density as water) water density (@0°C) = 1000 kg/m^3 (actual value is 999.8395 kg/m^3) = 1 g/ml volume = mass / density = (20 g) / (1 g/ml) = 20 ml
The volume of the object is the difference in water level before and after the object is added, which is 10 ml (30 ml - 20 ml). The density of the object is mass divided by volume, so 2g / 10 ml = 0.2 g/ml. Therefore, the density of the object is 0.2 g/ml.
