Liquid A has a density of 1.42g/cm^3 7cm^3 of liquid A is mixed with 125cm^3 of liquid B to make liquid C. Liquid C has a density of 1.05g/cm^3 Find the density of liquid B. Give your answer correct to 2 decimal places.

## Step1: First, we want to find the total mass and volume of mixture liquid C. ## Step2: Since we know its density is and density equals to mass divided by volume, from the total volume ( of liquid A added to of liquid B), we calculate that the total mass of liquid C would be mass .## Step3: Now, we can find the mass of liquid A because we know its density ( ) and its volume ( ). It would be same as calculating the mass of liquid A from: mass .## Step4: Therefore to find the mass of liquid B, subtract the mass of liquid A from the total mass of liquid C.## Step5: Indeed, once we have the mass of liquid B, we can find the density of liquid B by dividing its mass by its volume.### Step1 formula: ### Step2 formula: ### Step3 formula: ### Step4 formula: ### Step5 formula: # Calculation Part:## Step1 calculation:No calculation required at this point. ## Step2 calculation:Total volume of liquid C = volume of liquid A + volume of liquid B = Total mass of liquid C = ## Step3 calculation:Mass of liquid A = ## Step4 calculation:Mass of liquid B = ## Step5 calculation:Density of liquid B =
