Dr. House took two liquids of different densities (p_1=1500 kg/m^3; p_2 = 500 kg/m^3) are poured together into a 0.1 m^3 tank fi

lling it. If the resulting density of the mixture is 800 kg/m^3. He was asked to find the respective volume of liquids used.

We know that:
mass = density x volume
The volume of the total mixture is 0.1 m³
Let the first liquid be A and the second be B
Mass Total = Mass A + Mass B

800 x 0.1 = 1500Va + 500(0.1 - Va)
30 = 1000Va
Va = 0.03 m³
Vb = 0.1 - 0.03 = 0.07 m³

To make a 2 M solution of calcium chloride (CaCl2), you would place how many grams of CaCl2 into a container and then add how mu
belka [17]

Answer:

For a volume of 1 liter, we have a total mass of 220 grams of CaCl2 ( Option A)

Explanation:

<u>Step 1: </u>Given data

The concentration of the solution we want to make is 2M

2M = 2 moles/ L So the volume = 1L

The molar mass of CaCl2 is = 40 + 2*35 = 110g/mole

<u>Step 2:</u> Calculate number of moles

If we consider the volume = 1 L then for a concentration of 2M, this means the number of moles is 2

<u>Step 3:</u>  Calculate mass

The molar mass of CaCl2 = 110 g/mole

This means 110 grams per 1 mole

for 2 moles the mass is 220 grams

This means that for a volume of 1 liter, we have a total mass of 220 grams of CaCl2
