C=0.184 mol/L
n=0.113 mol
n=CV
V=n/C
V=0.113/0.184=0.614 L = 614 mL
You can determine the mass defect when you calculate for the absolute difference of the experimentally determined molar mass and the theoretical molar mass.
64Ni means there are 28 protons, 28 electrons and (64 - 28) = 36 neutrons. The mass of each proton is 1.0072766 amu; the mass of each electron is <span>0.00054 </span>amu; the mass of each neutron is <span>1.008664 amu.
Theoretical molar mass = 28(</span>1.0072766 amu) + 28(0.00054 amu) + 36(1.008664) = 64.5308 amu
Thus,
Mass defect = |63.9280 amu - 64.5308 amu| = <em>0.6028 amu</em>
Answer:
334.08 g
Explanation:
87 proof = 43.5%
in 1L of liquid there is 43.5% alcohol/ethanol
1L (43.5/100) = 0.435 L alcohol
we want density in g/L because that's the volume u have
density 0.798 g/mL = 798 g/L
multiply the volume of alcohol by its density to get grams
0.435 L(798 g/L) = 334.08 g
Carbon+oxygen= carbon dioxide
