Answer:

Molarity of a solution that contains 3.11 mol of NaNO3 is 1,24 M

Explanation:

We understand molarity as the number of moles of solute that are contained in 1 L of solution, then if in a solution of 2.50 L we have 3.11 moles, it remains to calculate how many moles do we have in 1 liter.

2,50 L .......... 3,11 moles

1 L .................. x

X = ( 1 L x 3,11 moles) / 2,50 L = 1,24

The teacher prepares 2.50 liters (l) of a salt solution for a class experiment. how many quarts (qt) are in 2.50 l? (1 l =1.06 q

trasher [3.6K]

The teacher prepares 2.50 liters (l) of a salt solution for a class experiment, in this quantity 2.65 quartz are present.

<h3>What is conversion factor?</h3>

Conversion factor is a quantity which will be multiplied or divide with any other measurement for the conversion of that measurement.

Given that quantity of salt solution = 2.50 L

We know that, 1 L = 1.06 qt

Here conversion factor is 1.06 qt/L as it will be multiplied on given measurement to convert into quartz as:

2.50L = 2.50L × 1.06qt/L = 2.65qt

Hence required value is 2.65qt.

How many moles of oxygen are produce dif 11.0 mol of al are produced

ycow [4]

Answer:

8.25 moles

Explanation:

Given parameters:

Number of moles of Al produced = 11 moles

Unknown:

Number of moles of oxygen produced = ?

Solution:

To solve this problem, we need to understand the problem.

The decomposition of an aluminium oxide must has produced oxygen and aluminium,

2Al₂O₃ → 4Al + 3O₂

now since the known is the oxygen gas; we can find the unknown aluminium:

3 mole of O₂ was produced with 4 mole of Al

x mole of O₂ will be produced with 11 moles of Al

x = $\frac{3 x 11}{4}$ = 8.25 moles
