Estimate the mass of water on the earth. The density of water is 1000kgm^-3 . Give answer to 1 significant figure. Here is a approximation you can use: Looking at charts of the oceans, we see that the depth is typically several thousand m (and a serious search tells me the average depth is 4700m) .The radius of the earth is about 6000km .The surface area of a sphere is 4πR².

The starship enterprise is caught in a time warp and spock is forced to use the primitive techniques of the 20th century to determine the specific heat capacity of an unknown mineral. the 125-g sample was heated to 96.3°c and placed into a calorimeter containing 85.9 g of water at 20.0°c. the heat capacity of the calorimeter was 14.2 j/k. the final temperature in the calorimeter was 24.5°c. what is the specific heat capacity (in j/g°c) of the mineral? enter to 4 decimal places.
