The pressure on 2.50 L of gas is changed from 4.5 atm to 2.2 atm. What is the new volume of gas?

swat32

Answer:

Explanation:

The new volume can be found by using the formula for Boyle's law which is

$P_1V_1 = P_2V_2$

Since we are finding the new volume

$V_2 = \frac{P_1V_1}{P_2} \\$

From the question we have

$V_2 = \frac{2.5 \times 4.5}{2.2} = \frac{11.25}{2.2} \\ = 5.1136666...$

We have the final answer as

Using the balanced equation given below, calculate the number of moles of CaBr2 produced in the reaction of 5.0 moles of AlBr3.

allochka39001 [22]

Answer:

7.5 moles of CaBr2 are produced

Explanation:

Based on the equation:

2AlBr3 + 3CaO → Al2O3 + 3CaBr2

<em>2 moles of AlBr3 produce 3 moles of CaBr2 if CaO is in excess.</em>

<em />

Using this ratio: 2 moles AlBr3 / 3 moles CaBr2. 5 moles of AlBr3 produce:

5 moles AlBr3 * (3 moles CaBr2 / 2 moles AlBr3) =

<h3>7.5 moles of CaBr2 are produced</h3>

Find the volume of an object that has a density 0f 3.14g/mL and a mass of 87.3g

pav-90 [236]

Answer:

<h3>The answer is 27.80 mL</h3>

Explanation:

The volume of a substance when given the density and mass can be found by using the formula

$volume = \frac{mass}{density} \\$

From the question

mass = 87.3 g

density = 3.14 g/mL

We have

$volume = \frac{87.3}{3.14} \\ = 27.8025477...$

We have the final answer as
