Using coupons seems like an old-fashioned, time-consuming way to save a few cents on the products you buy at the grocery store. After all, most coupons don't usually have a face value of more than $1 and, quite often, they're worth far less. But done properly, couponing can save you thousands of dollars every year.

How many moles are 3.20 x102 formula units of calcium iodide?
DedPeter [7]

The number of moles in 3.20 x 10² formula units of calcium iodide is 0.053 moles.

<h3>How to calculate number of moles?</h3>

The number of moles in the formula units of a substance is calculated by dividing the formula unit by Avogadro's number.

According to this question, 3.20 x 10² formula units are in calcium iodide. The number of moles is as follows:

no of moles = 3.20 x 10²² ÷ 6.02 × 10²³

no of moles = 0.53 × 10-¹

no of moles = 0.053 moles

Therefore, the number of moles in 3.20 x 10² formula units of calcium iodide is 0.053 moles.

the compound diborane can be used as a rocket propellant. what is the percent composition of boron in diborane
Blababa [14]

Answer:

78.14 % B; 21.86 % H

Step-by-step explanation:

The formula of diborane is B₂H₆.

The masses of each element are:

2B  = 2 × 10.81    = 21.62    u

6H = 6 ×   1.008 = <u>  6.048  u </u>

             TOTAL =  27.67    u


% B = 21.62/27.67 × 100

        = 78.14 %

% H = 6.048/ 27.67

        = 21.86 %
