an empty beaker is weighed and found to have a mass of 130g. a measuring cylinder contains 50cm3 of an unknown liquid. all the liquid is poured into the beaker which is again weighed and found to have a mass of 170 g. calculate the density of the liquid. pleasee with explanation)

Answer:0.8 g/cm^3Explanation:mass of liquid = mass of beaker + liquid - mass of beaker= 170g -130g = 40 gdensity = mass/ volumetherefore:density of volume = [tex]\frac{40g}{50cm^3} = 0.8 g/cm^3[/tex]where need be for 3 significant figure or 2 decimal place, just add zeros at the back of the 8
