Answer:
pretty sure its Scientific laws are statements about observed experimental facts, while theories are explanations of natural phenomena.
Answer is: <span>molecular formula of retinol is C</span>₂₀H₃₀O.
n(C) = 83,84 g ÷ 12 g/mol.
n(C) = 6,99 mol.
n(H) = 10,58 ÷ 1,008 g/mol.
n(H) = 10,5 mol.
n(O) = 5,58 g ÷ 16 g/mol.
n(O) = 0,348 mol.
n(C) : n(H) : n(O) = 6,99 mol : 10,5 mol : 0,348 mol /:0,348.
n(C) : n(H) : n(O) = 20 mol : 30,1 mol : 1.
It would be 10% concentrated, not 100%
the statement is false
Answer:
Mass = 0.000176 gram
Steps:
m = V × ρ
= 20 milliliter × 8.8 gram/cubic meter
= 2.0E-5 cubic meter × 8.8 gram/cubic meter
= 0.000176 gram
Explanation:
Water go through areas of high to low concentration in this case osmosis.
