The 3 indicates the third electron shell. (Which has only 1 electron in it in this configuration)
Hope this helps! :)
1 mmol --------------------- 1000 <span>µmol
( mmol ) -------------------- </span> 38231 µmol
mmol = 38231*1 / 1000
mmol = 38231/ 1000
=> 38.231 mmol
Answer is: f<span>ormula for the hydrated compound is CuSO</span>₄·3H₂O.
ω(H₂O) = 25,3% = 0,253.
ω(CuSO₄) = 100% - 25,3%.
ω(CuSO₄) = 74,7% = 0,747.
ω(H₂O) : M(H₂O) = ω(CuSO₄) : M(CuSO₄).
0,253 : M(H₂O) = 0,747 : 159,6 g/mol.
M(H₂O) = (0,253 · 159,6 g/mol) ÷ 0,747.
M(H₂O) = 54 g/mol.
N(H₂O) = 54 g/mol ÷ 18 g/mol.
N(H₂O) = 3.
Answer:elementary substance
Explanation:
Answer:
Weight = 98 kg.m/s^2
= 98 N.
Explanation:
Weight of an object is defined as the product of mass of the object and the acceleration due to gravity acting on the object. Its unit is Newton which is denoted as N and is also equivalent to kg.m/s^2.
Mass of the object = 10 kg
Acceleration due to gravity, g = 9.8 m/s^2
Weight = m*g
= 10 kg * 9.8 m/s^2
= 98 kg.m/s^2
= 98 N
