What is the mass, in grams, of 1.26 mol of water, H2O?

Masteriza [31]

Answer:

The mass of 1.26 mole of water, H₂O, is 22.68 grams

Explanation:

Molar mass is the amount of mass that a substance contains in one mole. In other words, the molar mass of an atom or a molecule is the mass of one mole of that particle and its unit is g/mole.

In this case, being:

H: 1 g/mole
O: 16 g/mole

the molar mass of water H₂O is:

H₂O= 2*1 g/mole + 16 g/mole= 18 g/mole

Then you can apply the following rule of three: if 18 grams are present in 1 mole of H2O, how much mass is present in 1.26 moles of water?

$mass=\frac{1.26 moles*18 grams}{1 mole}$

mass= 22.68 grams

<u><em>The mass of 1.26 mole of water, H₂O, is 22.68 grams</em></u>

Balance the following chemical equation I would give anyone the brainiest for answering.

serg [7]

<u>Answer :</u>

Part 13:

The balanced chemical reaction will be:

$Cu(NO_3)_2+Na_2SO_4\rightarrow CuSO_4+2NaNO_3$

Part 14:

The balanced chemical reaction will be:

$Cu(NO_3)_2+Na_2C_2O_4\rightarrow CuC_2O_4+2NaNO_3$

Part 15:

The balanced chemical reaction will be:

$Cu(NO_3)_2+2KOH\rightarrow Cu(OH)_2+2KNO_3$

<u>Explanation :</u>

Balanced chemical reaction : It is defined as the reaction in which an individual element of an atom present on reactant side must be equal to product side.

Part 13:

The balanced chemical reaction will be:

$Cu(NO_3)_2+Na_2SO_4\rightarrow CuSO_4+2NaNO_3$

Part 14:

The balanced chemical reaction will be:

$Cu(NO_3)_2+Na_2C_2O_4\rightarrow CuC_2O_4+2NaNO_3$

Part 15:

The balanced chemical reaction will be:

$Cu(NO_3)_2+2KOH\rightarrow Cu(OH)_2+2KNO_3$

A certain shade of blue has a frequency of 7.02 × 1014 Hz. What is the energy of exactly one photon of this light?

ruslelena [56]

<span>The energy (E) per photon is expressed by Planck's equation: E = hf, where f is
the frequency and h is Planck's constant, experimentally determined to be
6.625 * 10**-34 joule-seconds. So to find E, we multiply h by the frequency
and obtain E = hf = (6.625 * 10**-34)(7.0 * 10**14) = 46.375 * 10**-20 joule
or in standard notation, E = 4.6375 * 10**-19 joule per photon.

Hope this answers your question.Sorry if I calculated wrong.</span>
