An object has a mass of 94g, and a volume of 120 cm3, what is its density?
a) 783333 g/cm3
b) 780 kg/m3
To find the density of an object, we use the formula: density = mass / volume.
In this case, the mass of the object is given as 94g, and the volume is given as 120 cm3.
To find the density, divide the mass by the volume: density = 94g / 120 cm3.
To compare the given options, we need to convert the units to the same system.
Option a) is given in g/cm3, so we can leave the answer as it is.
Option b) is given in kg/m3.
To convert grams to kilograms, divide the mass by 1000: 94g / 1000 = 0.094 kg.
To convert cm3 to m3, divide the volume by 1,000,000: 120cm3 / 1,000,000 = 0.00012 m3.
Now we have the mass in kg and the volume in m3:
density = 0.094kg / 0.00012 m3.
To calculate this, divide the mass in kg by the volume in m3: density = 0.094kg / 0.00012 m3.
So, the density of the object is 783333 g/cm3 (option a).
