To determine the mass of oxygen per gram of sulfur for sulfur dioxide, we simply obtain the ratio of the mass of oxygen and the mass of sulfur produced from the decomposition of sulfur dioxide. All other values given in the problem statement above are just to confuse us that the question is a difficult one. We do as follows:
mass of oxygen per gram sulfur = 3.45 g / 3.46 g
mass of oxygen per gram sulfur = 0.9971 g O2 / g S
question 1
moles = mass/molar mass of Al(OH)3
convert Kg to g
that is 1.09 x 1000=1090g
moles is therefore=1090g/78(molar mass of Al(OH)3)= 13.974 moles
question 2
moles=2.55g/327.2(molar mass of Pb(CO3)2= 7.79 x 10^-3 moles
from avogadro constant
1moles=6.02 x10^23 formula units
what about 7.79 x 10 ^-3
={(7.79 x 10^-3)moles x ( 6.02 x10^23)} /1 mole=4.69 x10^21 formula units

Answer:
The answer is c
Explanation:
200 divided by 100 is 2 and you can check that by multiplying 2 by 100.
Answer:
0 percent chance.
Explanation:
If it is a male then the mom has to be a carrier or have the trait because the dad will pass on a Y, and the trait for colorblindness is linked to the X. If it is a female, she needs 2 of those traits (one from each parent), and since the mom cannot give one, there is not a chance of the kids having colorblindness.
