How many grams of sulfur are present in 83.2 grams of sulfurdioxide?

Chemistry
1 answer:
mr Goodwill [35]3 years ago
3 0

Answer:

41.6 g

Explanation:

Calculation of the moles of SO_2 as:-

Mass = 83.2  g

Molar mass of SO_2 = 64.066 g/mol

The formula for the calculation of moles is shown below:

moles = \frac{Mass\ taken}{Molar\ mass}

Thus,

Moles= \frac{83.2\ g}{64.066\ g/mol}

Moles_{SO_2}= 1.2987\ mol

From seen from the formula,

1 mole of sulfur is present in 1 mole of SO_2

So,

1.2987 mole of sulfur is present in 1.2987 mole of SO_2

Moles of sulfur = 1.2987 mol

Molar mass of sulfur = 32.065 g/mol

Mass = Moles*Molar mass = 1.2987\times 32.065\ g = 41.6 g

What is the molarity (M) of .5 liter of a solution that has 205 g of NaCl dissolved in it?
jeka94

Answer:

<h2>Molarity = 7 mol / L</h2>

Explanation:

Since the mass of NaCl and it's volume has been given we can find the molarity by using the formula

<h3>C =  \frac{m}{M \times v}</h3>

where

C is the molarity

m is the mass

M is the molar mass

v is the volume

From the question

v = 0.5 L

m = 205 g

We must first find the molar mass and then substitute the values into the above formula

M( Na) = 23 , M( Cl) = 35.5

Molar mass of NaCl = 23 + 35.5 =

58.5 g/mol

So the molarity of NaCl is

C =  \frac{205}{0.5  \times 58.5}  \\ C =  \frac{205}{29.25}

C = 7.00854

We have the final answer as

<h3>Molarity = 7 mol / L</h3>

Hope this helps you

How many atoms are in a 3.5 mole sample of the element lithium?
seraphim [82]

Answer:

2.1 x 10^24

Explanation:

The number of atoms in a mole will always be the same. The fact that it's lithium is completely irrelevant.

One mole of anything is 6.022 x 10^23 atoms

So if we need to find the number of atoms in 3.5 mol we just need to multiply Avogadro's number by 3.5

3.5 x 6.022 x 10^23

= 21.077 x 10^23

To make it proper scientific notation the first number can't be greater than 10 so let's move the decimal place and increase the exponent

2.1077 x 10^24

Remove the numbers that aren't significant figures

2.1 x 10^24

Boom there's your answer

What is the ph of a buffer prepared by adding 0.506 mol of the weak acid ha to 0.609 mol of naa in 2.00 l of solution? the disso
sertanlavr [38]
Hello!

To solve this question, we first have to know the pKa of the acid:

pKa=-log(Ka)=-log(5,66*10^{-7})=6,25

Now, we can apply the Henderson-Hasselbach's equation to determine the pH of the buffer solution:

pH=pKa+ log( \frac{[NaA]}{[HA]} )= 6,25 + log(\frac{(0,609 mol/2L)}{(0,506 mol/2L)})=6,33

So, the pH of this buffer solution is 6,33

Have a nice day!

Brut [27]

Answer:Heat is a type of ENERGY. When absorbed by a substance, heat causes inter-particle bonds to weaken and break which leads to a change of state (solid to liquid for example). Heat causing a phase change is NOT sufficient to cause an increase in temperature.
