To calculate the density of an object, you can use the formula: density = mass/volume. Given that the mass is 78 g and the volume is 15 cm³, the density would be 78 g / 15 cm³ = 5.2 g/cm³. Therefore, the density of the object is 5.2 g/cm³.
Ethanol (USP grade) has a density of 0.810. From here we have to use the formula: d=m/v, where d is density, m, mass and v, volume. Solving for volume, we have v=m/d, therefore: v= 15/0.810 = 18.52 mL of ethanol are equivalent to 15g.
To find the density, divide the mass of the rock (15 grams) by its volume (30 milliliters). Density = mass/volume, so in this case 15 grams / 30 milliliters = 0.5 grams per milliliter. Therefore, the density of the rock is 0.5 g/mL.
Density of that object is 2.8
The density of the object is 3 grams per milliliter (15 grams / 5 milliliters).
The formula for density is mass/volume, hence the density is 15/5=3g/cm3
You need to know the volume because the density is the ratio mass/volume.
Density = Mass/Volume = 30/15 = 2 grams per millilitre.
density = mass/volume density = 15/20 = 3/4 units/ml
Mass = 15 gm Volume = 2 cubic cm Density = Mass/Volume = 15/2 = 7 and 1/2 or 7.5 g per cm3
To calculate the mass of benzene, use the formula: mass = volume x density. You need to know the volume of 0.1900 L of benzene at 15°C, which can be calculated using the ideal gas law or the formula for density (density = mass/volume). Once you have the volume, multiply it by the density to find the mass.
Density = mass/volume = 36/15 = 2.4 g per cm3
Density = Mass/Volume = 30/15 = 2 grams per mL.
By definition: density = mass / volume Solving for volume: volume = mass / density Please note that a boy will NOT have a density of 15, at least, not if you use anything remotely related to SI units. The density of a person is close to that of water - with a density of 1, or 1000, depending on the units used.
You need a unit for the mass, not just a number. In any case, the idea is to divide the mass by the volume.
To find the volume, you divide the mass by the density. In this case, the volume would be 5 ml (15 g ÷ 3 ml).
Density = Mass/Volume = 15/60 = 0.25 grams per millilitre.
