How many grams of Cl are in 465g of CaCl2

Chemistry
2 answers:
Rama09 [41]3 years ago
6 0
2 ways to do this
a. find %Cl in CaCl2
2 x 35.45g/mole = 70.9g Cl
70.9g Cl / 110.9g/mole CaCl2 = 63.93% Cl in CaCl2
0.6963 x 145g = 92.7g = mass Cl

b. determine moles CaCl2 present then mass Cl
145g / 110.9g/mole = 1.31moles CaCl2 present
2moles Cl / 1mole CaCl2 x 1.31moles = 2.62moles Cl
2.62moles Cl x 35.45g/mole = 92.7g Cl

Answer:

297.4332 grams of chlorine is present in 465 grams of calcium chloride.

Explanation:

Mass of calcium chloride = 465 g

Molar mass of calcium chloride = 111 g/mol

Moles of calcium chloride = \frac{465 g}{111 g/mol}=4.1892 mol

1 mol of calcium chloride has 2 moles of chlorine atoms.

Then 4.1892 moles of calcium chloride has:

2 \times 4.1892 mol=8.3784 mol of chlorine atoms

Mass of 8.3784 moles of chlorine atom:

8.3784 mol × 35.5 g/mol=297.4332 g

A local am radio station broadcasts at a wavelength of 349m, calculate the energy of the wavelength at which it is broadcasting?
Juli2301 [7.4K]

Answer:

E = 5.69x10⁻²⁸m

Explanation:

To solve this question we neeed to convert the wavelength in meters to energy in joules using the equation:

E = hc / λ

<em>Where E is energy in joules, h is Planck's constant = 6.626x10⁻³⁴Js</em>

<em>c is light constant = 3.0x10⁸m/s</em>

<em>And λ is wavelength in meters = 349m</em>

Replacing:

E = 6.626x10⁻³⁴Js*3.0x10⁸m/s / 349m

E = 5.69x10⁻²⁸m

How a cation is formed by an atom?​
fenix001 [56]

Answer:

Cations are positively charged atoms and hence we need to make the atom positively charged in order to get a cation

We know that an atom is neutral as a whole, so we have equal number of electrons and protons

since we cannot mess with the number of protons in an atom, we have to do it by altering the number of electrons

If we reduce the amount of electrons in an atom, the net charge will be positive and hence a cation will be formed
