Answer:

Explanation:

(KF)2(Al2O3)3(SiO2)6(H2O)

molecular formula

K₂F₂Al₆Si₆O₂₂H₂

2 x 39 + 2 x 19 + 6 x 27 + 6 x 28 + 22 x 16 + 2 x 2

=  78 + 38 + 162+ 168+ 352+ 4

= 802

Percentage of K = 78 x 100 / 802

= 9.72 %

Percentage of F = 38 x 100 / 802

= 4.74 %

Percentage of Al = 162 x 100 / 802

= 20.2  %

Percentage of Si = 168 x 100 / 802

= 20.9  %

Percentage of O = 352 x 100 / 802

= 43.9 %

Percentage of H = 4 x 100 / 802

= .54  %

A student dissolves 4.5 G of sodium chloride into 75 grams of water which of the following statements is correct regarding the r
Jobisdone [24]
"The vapor pressure will decrease and the boiling temperature will increase." When sodium chloride is added to water, the vapor pressure above the resulting salt solution is less than the vapor pressure above the pure water, and the boiling point of the salt solution will be greater than the boiling point of pure water. This results from the introduction of salt molecules to water, in which the salt solution needs a higher temperature for the vapor pressure to be equal to the pressure of the atmosphere.

When determining the mass of product used or reactant consumed, the number of moles must be determined before comparing two subs
FromTheMoon [43]

Answer:

moles react.

Explanation:

In a chemical reaction equation, we know that chemical species react in moles. It is actually the moles of the individual chemical species that participate in a chemical reaction and not the masses of those species.

In solving stoichiometric problems, it is mandatory to use moles as a conversion factor in calculating the mass of product formed or the mass of reactant consumed. We often read off the number of moles that reacted from the balanced reaction equation and then convert the reacting mass of species given to the number of moles of that specie that actually participated in the reaction in order to obtain any required information from a reaction.

PLS HELP ASAP i really need an answer a correct one
nata0808 [166]

Answer: 67.23 L

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number 6.023\times 10^{23} of particles.

To calculate the number of moles, we use the equation:

\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}

Putting in the values we get:

\text{Number of moles of methane}=\frac{48g}{16g/mol}=3moles

1 mole of methane occupies = 22.4 L

Thus 3 moles of methane occupy = \frac{22.4}{1}\times 3=67.23L

Thus volume of 48 grams of methane gas is 67.23 L
