Missing in your question: the molarity of H2SO4 M = 0.1 M
and the equivalence point (mL) = 19.31 mL = 0.019 L
So by using the molarity formula:
molarity of H2SO4 = no of moles of H2SO4 / Volume L
So by substitution:
0.1 M = no of moles of H2SO4 / 0.019 L
∴ no of moles of H2SO4 = 0.1 M * 0.019 L
= 0.0019 mol
Answer:
1 Å = 1.0 × 10⁻¹ nm
1 Å = 1.0 × 10² pm
Explanation:
Angstrom is the unit of the length which is equal to one ten-billionth of the metre or 10⁻¹⁰ m. It is represented by the symbol is Å .
Angstrom is not part of SI system of the units, but it is considered as a part of metric system.
Angstrom is used often in natural sciences as well as technology in order to express the sizes of atoms / molecules, and the lengths of the chemical bonds, etc.
1 Å = 10⁻¹⁰ m
1 nm = 10⁻⁹ m
1 pm = 10⁻¹² m
So,
1 Å = 1.0 × 10⁻¹ nm
1 Å = 1.0 × 10² pm
Answer:
<em><u>universal law of </u></em><em><u>gravitation</u></em>
Explanation:
According to Newton's law of gravitation, every particle in universe attracts every other particles with a force which is directly proportional to the product of their masses and inversely proportional to the square of distance between their centres!
Consider two particles having masses m1 and m2 and are apart r units, then the gravitational force acting between them is given by
Where G is universal gravitational constant or proportionality constant!!

It would typically be around 5000 seconds(83.33) minutes for the water to freeze.
