0.25 moles of CO2 is present in 11 grams of CO2.

Explanation:

A mole represents the number of chemical entities in an element or molecule.

Number of moles of an element or molecule is determined by the formula:

The Number of moles (n) = weight of the atom given  ÷ atomic or molecular weight of the one mole of the element or molecule.

Themolar mass of one mole of carbon dioxide is:

12+ ( 16×2)

= 44 gram/mole

The given weight is 44 grams of carbon dioxide.

Putting the values in the equation,

n= 11 gms÷44 gms/ mole

n   = 0.25 mole

frozen [14]
<span>Cations mix with anions, so you know NH4+ won't mix with K+ and SO4(2-) won't miix with F-. For the reason that NH4+ and F- together have single charges, they'll mix in a 1:1 ratio, NH4F. There's two charges on SO4(2-), so it'll need two K+ to mix with, K2SO4.</span>

What volume will 0.405 g of krypton gas occupy at STP?
Rufina [12.5K]

Answer:

The answer to your question is V = 0.108 L or 108 ml

Explanation:

Data

Volume = ?

mass = 0.405 g

Temperature = 273°K

Pressure = 1 atm

Process

1.- Convert mass of Kr to moles

                  83.8 g of Kr -------------------- 1 mol

                     0.405 g     -------------------  x

                     x = (0.405 x 1) / 83.8

                     x = 0.0048 moles

2.- Use the Ideal gas law to solve this problem

                   PV = nRT

- Solve for V

                      V = nRT / P

- Substitution

                      V = (0.0048)(0.082)(273) / 1

- Simplification

                       V = 0.108 / 1

- Result

                       V = 0.108 L
