Calculate the atoms of hydrogen in 52.0 g of H2O.

Chemistry
1 answer:
Zarrin [17]2 years ago
5 0

Answer:

34.81 ×10²³ atoms

Explanation:

Given data:

Mass of water = 52.0 g

Number of atoms of hydrogen = ?

Solution:

Number of moles of water:

Number of moles = mass/molar mass

Number of moles = 52.0 g/ 18 g/mol

Number of moles = 2.89 mol

1 mole of water contain 2 mole of hydrogen.

2.89 mole of water contain 2.89× 2= 5.78 moles of hydrogen.

Number of atoms of hydrogen:

1 mole = 6.022×10²³ atoms

5.78 mol ×  6.022×10²³ atoms / 1mol

34.81 ×10²³ atoms

P₄O₁₀ + 6H₂O → 4H₃PO₄
The equation shows us that the molar ratio of
P₄O₁₀ : 6H₂O = 1:6

We also know that one mole of a substance contains 6.02 x 10²³ particles. We can use this to calculate the moles of water.
moles(H₂O) = (5.51 x 10²³) / (6.02 x 10²³)
= 0.92 mole
That means moles of P₄O₁₀ = 0.92 / 6
= 0.15

Each mole of P₄O₁₀ contains 4 moles of P. 
moles(P) = 4 x 0.15 = 0.6 mol
Mr of P = 207 grams per mol
Mass of P = 207 x 0.6
= 124.2 grams

A 160g radioactive sample is left undisturbed for 12.5 hours. At the end of that period, only 5.0g remain. What is the half-life
11Alexandr11 [23.1K]

it would be 26 because once you divide 160g by 5.0g and add 12.5 you would get 26

hope this helps

The appropriate mixing ratio for a solution to kill blood borne pathogens is 1 part chlorine to 10 parts water if you are mixing
jarptica [38.1K]

To solve this problem, all we have to do it to make use of the principle of ratio and proportion. We are given the following ratio:

1 part Chlorine / 10 parts Water

Now to determine the amount of chlorine needed for 15 ounces of water, all we have to do is to use proportion. Let us say that the amount of Chlorine needed is x, therefore:

1 part Chlorine / 10 parts Water = x / 15 ounces Water

so,

1 / 10 = x / 15

Therefore calculating for x:

x = 15 / 10

<span>x = 1.5 ounces of Chlorine</span>
