The mass and volume of a planet are given in the table belo Work out the density of the planet. Give your answer in standard index form. Mass & 7 times 10^29 mathrm(~kg) Volume & 2 times 10^26 mathrm(~m)^3 Density & mathrm(kg) / mathrm(m)^3 [ ( density )=( ( mass ))/( ( volume )) ]

## Step1: The first step involves understanding the problem and identifying the values given. In this case, we are told that the mass of the planet is kg. and its volume is m³. We need to calculate the density from the given information. ## Step2: Recall that the formula for calculating the density is the mass divided by the volume it occupies. This is stated in mathematical symbols as: ### Substituting the given mass and volume from the problem into the formula, we get ### ## Step3:Solve the equation to find the value for the density:One structural method to solve such calculations, especially when handling a calculation involving numbers expressed in Scientific Notation, is to individually divide the figures and then the powers.Thus,### Which is simplified to###
