Answer:
a) 0.13 g = 0.13X0.001 kg = 1.3 X 10⁻⁴ kg
b) 232 Gg = 232 X 1000000 kg = 2.32 X 10⁸ kg
c) 5.23 pm = 5.23 X 10⁻¹² m
d) 86.3 mg = 86.3 X 10⁻⁶Kg = 8.63 X 10⁻⁵Kg
e) 37.6 cm = 37.6 X 10⁻² m = 3.76 X 10⁻¹m
f) 54 = 5.4 X 10¹
g) 1 Ts = 10¹² seconds
h ) 27 ps = 27 X 10⁻¹² s= 2.7 X 10⁻¹¹ s
i) 0.15 mK = 1.5 X10⁻⁴ K
Explanation:
A scientific notation is a representation of any number which is very large or very small. It is simplification of writing a number.
The SI units of
i) weight = Kg
ii) length = meter
iii) time = second
iv) temperature = K
a) 0.13 g = 0.13X0.001 kg = 1.3 X 10⁻⁴ kg
b) 232Gg
1 Gg = 1000000 kg
232 Gg = 232 X 1000000 kg = 2.32 X 10⁸ kg
c) 5.23 pm
1 pm = 10⁻¹² m
5.23 pm = 5.23 X 10⁻¹² m
d) 86.3 mg
1mg = 10⁻⁶Kg
86.3 mg = 86.3 X 10⁻⁶Kg = 8.63 X 10⁻⁵Kg
e) 37.6cm
1 cm = 10⁻² m
37.6 cm = 37.6 X 10⁻² m = 3.76 X 10⁻¹m
f) 54 (no units)
54 = 5.4 X 10¹
g) 1 Ts = 10¹² seconds
h ) 27 ps
1 ps = 10⁻¹² s
27 ps = 27 X 10⁻¹² s= 2.7 X 10⁻¹¹ s
i) 0.15 mK
1mK = 10⁻³ K
0.15 mK = 1.5 X10⁻⁴ K
Answer:
121.78 g
Explanation:
You multiply the mols by the grams in one mol.
It receives blood from the whole body. Blood from the lungs enters the heart through the pulmonary vein into the left atrium. ... - Has ventricles that has thicker walls thus more muscular than auricles generating higher pressure to pump blood over long distances.
Simply look at the periodic table and fill in what you know based on the table
The number of protons = atomic number
The number of electrons, Which is the same as the atomic number for atoms.
The number of valence electrons that is given by the group that the element is in, the top number of each column in the periodic table.
