Question

question 1 - 4
a student is investigating the relationship between mass, volume, and density of liquids. she records that a certain liquid has a density of 1.2 g/ml. the student then measures the
250 ml and wants to calculate its mass.
what would be the mass of the liquid?
d = m/v
350g
200g
250g
300g

Explanation:

Step1: Rearrange the density formula

Given \(D = \frac{m}{V}\), we can solve for \(m\) (mass) by multiplying both sides by \(V\) (volume). So \(m=D\times V\).

Step2: Substitute the values

We know \(D = 1.2\space g/mL\) and \(V = 250\space mL\). Then \(m=(1.2\space g/mL)\times(250\space mL)\).

Step3: Calculate the mass

\(m = 1.2\times250=300\space g\)

Answer:

\(300g\)
