2.2 pounds in a kilogram.
70/2.2 = 31.818 kg of the child.
<span>10mg/kg and the tylenol is 80 mg per tables.
Child should take 318.18 mg divide that by per tablet 318.18/80 = 3.977 tablets. </span>
<span>We are using 1 sig fig, so that would make our answer be 4 tablets.</span>
Kc = [CS2] / [S2][C] but, since C is solid, it doesn't fit here
<span>Kc = [CS2] / [S2] </span>
<span>S2(g) + C(s) ---> CS2(g) </span>
<span>13.8mole S2 / 6.05L = 2.28M </span>
<span>Kc = x / 2.28-x </span>
<span>9.4 x (2.28-x) = x </span>
<span>21.43 - 9.4x = x </span>
<span>21.42 = 10.4x </span>
<span>x = 2.05M = [CS2] </span>
<span>2.05M x 6.05L = 12.46moles </span>
<span>12.46moles x 76gmole = 946.96g CS2</span>
From the atmosphere
Hope this helps!
The molar mass is calculated by looking up the relative atomic mass values on a periodic table. The relative atomic mass is a value without units that is calculated on a Carbon-12 scale.
By looking at the periodic table (values will be to 3 significant figures [<em>2</em><em> for hydrogen though]</em>):
Molar mass (M) of 1 mole of Carbon = 12.0 g/mol
Molar mass (M) of 1 mole of Hydrogen = 1.0 g/mol
Molar mass (M) of 1 mole of Oxygen = 16.0 g/mol
So the molar mass is essentially the relative atomic mass (RAM), but molar mass has a unit, but RAM doesn't (it is a ratio).
Given the formula is C6H12O6 (without putting the numbers as subscripts), we can calculate as follows:
M (C6H12O6) = (6 x 12.0) + (12 x 1.0) + (6 x 16.0)
= 72.0 + 12.0 + 96.0
= 180.0 g/mol
Hope it's right :D
C because it has to do with opposite motions and stuff
