The atomic mass of Ag is 107.87. The atomic mass of Cl is 35.45. The molecular mass of AgCl is therefore 143.32. 0.025 mols of AgCl were produced. This required .0125 mols of the original metal chloride since it has 2 chlorine atoms per molecule and AgCl only has one per molecule.
The molecular mass of mCl2 must be 127.2 in order for 1.59g of mCl2 to be .0125 mols. The molecular mass of m can be calculated by subtracting the molecular mass of 2 chlorine atoms
127.2-35.45-35.45=56.30</span>
Answer:
39,5 grams should be obtained of NaCl
Explanation:
We calculate the weight of 1 mol of NaCl:
Weight 1 mol NaCl= Weight Na + Weight Cl= 23g + 35,5g=58,5 g/mol
4,5M--> 4,5 moles NaCl in 1000ml (1L) of solution
1000ml-----4,5 moles NaCl
150 ml------x=(150 mlx4,5 moles NaCl)/1000ml=0,675 moles NaCl
1 mol NaCl--------------58,5 grams
0,675molesNaCl---x= (0,675molesNaClx58,5 grams)/1 mol NaCl
x= 39,4879 grams
Answer:
The higher the vapor pressure of a liquid at a given temperature, the lower the normal boiling point of the liquid.
Explanation:
Answer:
The word (Carbon Dioxide) is a gas that takes up around 0.03% of the atmosphere and can be dangerous if inhaled for too long.
The scientific formula for the gas (Carbon Dioxide) is CO2
(1 carbon + 2 oxygen)
