The molar mass of CuCl2 is 134.45 g/mol; therefore, you divide 2.5 g of CuCl2 by 134.45 g of CuCl2 leaving you with 0.019 moles.
I hope this works.
PLEASE GIVE ME A BRAINIEST CROWN.
Answer:
Sp3 hybridization
Explanation:
The NH3 molecule, which consists of one lone pairs and three bond pair of electron on its valance shell due to lone pair bond pair repulsion makes bond angle of 107.5°resulting distorted tetrahedral geometry.
Hybridization =no. of bond pair +lone pair=3+1=4=sp3 hybridization
For the first one the input force would be where the grip part is
The mass of butane gas at the given volume and Standard temperature and pressure is 0.0022g.
<h3>What is Ideal Gas Law?</h3>
The Ideal gas law or general gas equation emphasizes on the state or behavior of a hypothetical ideal gas. It states that "the pressure multiplied by volume is equal to moles multiply by the universal gas constant multiply by temperature.
It is expressed as;
PV = nRT
Where P is pressure, V is volume, n is the amount of substance, T is temperature and R is the ideal gas constant ( 0.08206 Latm/molK )
Given the data in the question;
- Volume of the gas V = 3L
- At STP; P = 1.0atm, T = 273.15K
- Amount of gas n = ?
PV = nRT
n = PV / RT
n = ( 1.0atm × 3.00L ) / ( 0.08206 Latm/molK × 273.15K )
n = 3.00Latm / 22.41 Latm/mol
n = 0.13mol
Now, since Molar mass of brutane gas is 58.12 g/mol.
Mass = n × Molar mass
Mass = 0.13mol × 58.12 g/mol
Mass = 0.0022g
Therefore, the mass of butane gas at the given volume and Standard temperature and pressure is 0.0022g.
