Question

1. an empty 250 - milliliter beaker has a mass of 60 grams. when 100 milliliters of oil is added to the beaker, the total mass is 140 grams. the density of the oil is approximately a) 0.8 g/ml b) 1.7 g/ml c) 0.6 g/ml d) 1.4 g/ml

Explanation:

Step1: Calculate the mass of the oil

The mass of the oil \(m\) is the total mass minus the mass of the empty beaker.
\(m = 140 - 60=80\) grams

Step2: Use the density formula

The density formula is \(
ho=\frac{m}{V}\), where \(V = 100\) milliliters and \(m = 80\) grams.
\(
ho=\frac{80}{100}=0.8\) g/ml

Answer:

A. \(0.8\) g/ml
