Calculate the formula mass for the compound tin(IV) sulfate.
stellarik [79]
The molecular formula for tin(IV)  sulfate is Sn(SO₄)₂.
mass of sulfur S = 32.065
as there is 2 sulfur in tin (IV) sulfate = 32.065 x 2 = 64.13
mass of oxygen = 15.999 and there are 8 oxygen atoms in the formula; 
8 x 15.999 = 127.992
mass of tin = 118.71
now add all the masses = 64.13 + 127.992 + 118.71 = 310.832 
formula mass of tin(IV) sulfate is 310.832

How many moles are there in 8.50 X 1024 molecules of sodium sulfate, Na2SO3?
DiKsa [7]
Hello!

To solve this question, we need to use the Avogadro's Number, which is a constant first discovered by Amadeo Avogadro, an Italian scientist. He discovered that in a mole of a substance, there are 6,02*10²³ molecules. Using this relationship, we apply the following conversion factor:

8,50* 10^{24}molecules* \frac{1 mol Na_2SO_3}{6,02* 10^{23}molecules}=14,12 molesNa_2SO_3

So, 8,50 * 10²⁴ molecules of Na₂SO₃ represent 14,12 moles of Na₂SO₃ 

Have a nice day!

When you convert feet to inches, how do you decide which portion of the conversion factor should be in the numerator and which i
Inessa05 [86]

Answer : The conversion used is, 1\text{ feet}=12\text{ inches}

Explanation :

The conversion used :

1\text{ feet}=12\text{ inches}

For example : To convert 10 feet into inches.

1\text{ feet}=12\text{ inches}

10\text{ feet}=10\text{ feet}\times \frac{12\text{ inches}}{1\text{ feet}}

                    =120\text{ inches}

From this we conclude that, the conversion factor used in the numerator and denominator for 1 feet should be, \frac{12\text{ inches}}{1\text{ feet}}
