C = n/V
n = C×V
n = 4,41M × 1,25L
n = 5,5125 mol
mKI: 39+127 = 166 g/mol
1 mol --------- 166g
5,5125 mol --- X
X = 166×5,5125 = 915,075g KI

Since a water molecule is H2O, you would divide 126 hydrogen molecules by 2, and you would get 63. That means you have 63 double hydrogen molecules, and 58 oxygen molecules to pair up with them. So that means you could have 58 molecules of water, with 5 double hydrogen molecules, so basically 10 extra molecules of hydrogen along with the H2O molecules. Hope I helped! :)
<span>7.86 g / 1 mL
divide g by 1000 for kg and divide mL by 100 for dL
</span>0.00786 kg / 0.01 dL = 0.786 kg/dL (density)
3.67 kg / 0.786 dL = 4.6692 dL
Another approach:
3.67kg > (3.67kg x 1000) = 3670 grams
3670 grams / 7.86 (density) = 466.92 mL
466.92 mL (divide by 100 for dl) = 4.6692 dL
There are 7 valence electrons in the atom :)
