If something has a mass of 1.899 x 10 (to the power of 27) and a density of 1.24 x 10 (to the power of 3) kg m (minus3), what is the volume? Volume is given by mass divided into density
You should give your answer in scientific notation to the appropriate number of significant figuresPlease help! I dont have a clue how to work this out

watch how the units cancel
1.899e27 kg / 1240 kg/m³ = 1.53e24 m³
or 1.53e15 km³
which is about the volume of Jupiter.

// You omitted the units for mass, so I'm going to assume it's kg
mass = density x volume
mass 1.899 x 10²⁷ kg
volume = ---------- = ------------------------
density 1.24 x 10³ kg m⁻³
volume = 1.53 x 10²⁴ m³ .........................ANS

There's a mistake in your wording. The formula for volume is mass divided *by* density (not *into* density).
Volume = density / mass <-- mass divided *into* density (WRONG!)
Volume = mass / density <-- mass divided *by* density (CORRECT)
You also didn't provide any units for your mass to know if there is a unit conversion.
Assuming your mass is in *kilograms*, you just divide the two numbers and that gives you the volume in cubic meters (m^3).
1.889 x 10^27 (kg) / (1.24 x 10^3) (kg/m^3)
= (1.889 / 1.24) * (10^27 / 10^3) (m^3)
≈ 1.52 * 10^24 m^3
