what is the formula and answer for the following question...

The density of Sprite is o.45g and the density of Pepsi is 2.4g. Both have a volume of 4 cm(cubed) What is the mass of both sodas?

add them up then divide by 2 and theres your answer duh

You need to clarify the question. Density is measured in mass/unit volume. You have the mass listed for each but no volume; i.e., the density of Sprite is 0.45 g/??cc (whatever that may be) and the density of Pepsi is 2.5 g/??cc (whatever that value may be). I suspect you may have reversed the names for density and mass.

what is the density of material that has a mass of 54.457g and a volume of 13.5cm?

To calculate the mass of both sodas, we need to use the formula:

Mass = Density x Volume

Let's start with Sprite. Given that the density of Sprite is 0.45g/cm³ and its volume is 4 cm³:

Mass of Sprite = 0.45g/cm³ x 4 cm³ = 1.8g

Now let's move on to Pepsi. Given that the density of Pepsi is 2.4g/cm³ and its volume is also 4 cm³:

Mass of Pepsi = 2.4g/cm³ x 4 cm³ = 9.6g

Therefore, the mass of Sprite is 1.8g and the mass of Pepsi is 9.6g.
