Calculate the density of chloroform

Rina8888 [55]

Answer: The density of chloroform is 1.47 g/mL

Explanation : Given,

Volume = 40.5 mL

Mass of cylinder = 85.16 g

Mass of cylinder and liquid = 145.10 g

First we have to calculate the mass of liquid (chloroform).

Mass of liquid = Mass of cylinder and liquid - Mass of cylinder

Mass of liquid = 145.10 g - 85.6 g

Mass of liquid = 59.5 g

Now we have to calculate the density of liquid (chloroform).

Formula used:

$Density=\frac{Mass}{Volume}$

Now putting g all the given values in this formula, we get:

$Density=\frac{59.5g}{40.5mL}$

$Density=1.47g/mL$

Therefore, the density of chloroform is 1.47 g/mL

__ CaSO4 + ____AIP --> ____Ca3P2 + ____AI2(SO4)3

4vir4ik [10]

Answer:

4.89 mol

Explanation:

Step 1: Write the balanced equation

This is a double displacement reaction.

3 CaSO₄ + 2 AIP ⇒ Ca₃P₂ + AI₂(SO₄)₃

Step 2: Establish the appropriate molar ratio

According to the balanced equation, the molar ratio of CaSO₄ to AlP is 3:2.

Step 3: Calculate the moles of AlP needed to react with 7.33 moles of CaSO₄

We will use the previously established molar ratio.

7.33 mol CaSO₄ × 2 mol AlP/3 mol CaSO₄ = 4.89 mol AlP
