Density of an apple.
Hi,
This is my first post could someone please help me solve this and show me how you come to the answer?
A net of 6 apples from Asda has a total mass of 1590g, measured to the nearest 10s, and the volume of one apple is 3.0 x 10to the power of 4cubed. Calculate the density of an apple. Give your answer in scientific notation and to the appropriate number of significant figures.
DENSITY=MASS/VOLUME (KG/VOLUME)
Any help would be appreciated

Just divide 1590/6 to get the (avg) mass of 1 apple. Then divide that by $\displaystyle 3x10^{4}$. Finally, convert to the desired units.
