the element is Ca with atomic number 20
Answer:
π = 29.3 atm
Explanation:
The osmotic pressure π is given by
π = i MRT, where i=Vant Hoff factor =2 for NaCl ( 2 moles ions/mol NacL)
M = molarity
R = 0.0821 Latm/molK
T = temperature K
Assuming density of solution is 1 g/mL
M= 35 g/58.44 gmol / 1 L = 0.60 M
π = 2.0 x 0.60 mol/L x 0.0821 Latm/kmol x 300K = 29.3 atm
Answer: It states that there is a fundamental limit to what one can know about a quantum system.
Explanation:
Answer is (b)
2,3,1 is the stoichiometry
The values in front of the elements are the stoichiometric values
(Since Al2Br6 has no value in front, it's considered 1)
Explanation:
1 mole is equal to 1 moles Al2O3, or 101.961276 grams.
