Calculate the number of moles of iodine in 7.68×10^25 molecules of I2
Dmitrij [34]

Answer:

<h2>127.57 moles</h2>

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

n =  \frac{N}{L} \\

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

n =  \frac{7.68 \times  {10}^{25} }{6.02 \times  {10}^{23} }   \\  = 127.574750...

We have the final answer as

<h3>127.57 moles</h3>

Hope this helps you

What volume of 5.00 × 10-3 m hno3 is needed to titrate 80.00 ml of 5.00 × 10-3 m ca(oh)2 to the equivalence point? what volume o
Dimas [21]

Answer:

= 160 mL

Explanation:

The equation for the reaction is;

Ca(OH)2 + 2HNO3 -----> Ca(NO3)2 + 2H2O

Moles of Ca(OH)2 =  0.080 L x 5.00^-3 M

                              = 0.0004 moles

From the reaction; 2 moles of HNO3 reacts with 1 mole of Ca(OH)2

Thus; moles of HNO3 = 0.0004 Moles × 2

                                    = 0.0008 moles

Volume = moles/ molarity

Therefore; volume of HNO3= 0.0008 Moles/ 5 × 10^-3 M

                                              <u>= 0.16 L or 160 mL</u>

An empty Erlenmeyer flask weighs 241.3 g. When filled with water (d = 1.00 g/cm³), the flask and its contents weigh 489.1 g. (a)
miskamm [114]

The answer is- Volume of flask = 247.8 cm^3 or 247.8 mL.

Density (d) is defined as mass of substance divided by its volume. Thus, if mass and density are known, then Volume can be determined.

What is the formula of volume in terms of density?

  • Let mass of substance be 'm' and volume be 'V'. Thus, as per the definition of density, it is expressed as-

d = \frac{m}{V}

Thus, volume can be expressed as-

V =\frac{m}{d}

  • Now, mass of empty flask = 241.3 g and the mass of  (flask + Water) = 489.1 g.

Thus, mass of water = 489.1\ g- 241.3\ g = 247.8\ g.

  • Thus, mass of water = 247.8 g and density of water =1.00\ g/cm^3. Its volume is calculated as-

V = \frac{247.8\ g}{1.00\ g/cm^3}=247.8\ cm^3

  • Hence, volume of flask = 247.8 cm^3 or 247.8 mL.
