1 cg ---------- 0.1 dg
457 cg ------- ?
457 x 0.1 / 1
= 45.7 dg
Answer:
the answer is protons and neutrons
Explanation:because
Answer:
8.83 moles of Hydrogen
Explanation:
We are told that 1.92 moles of H2 occupies 22.2 L at a certain pressure and temperature, and we are asked to calculate the quantity of moles of H2 are necessary to fill a container of 102.1 L. So, if the pressure and temperature are constant, then the equality expressed before 1.92 H2 moles = 22.2 L maintains. Therefore, we can calculate what is being asked as follows:
22.2 L ----- 1.92 H2 moles
102.1 L ---- x = (102.1 L × 1.92 H2 moles)/22.2 L = 8.83 H2 moles
This means that 8.83 H2 moles are necessary to fill a 102.1 L container at a certain pressure and temperature.
A 0.12 M solution of an acid that only slightly ionizes in solution would be termed a weak acid. Weak acids are acids which do not completely dissociate in water. Thus lowering the presence of hydronium ions which measures the pH of an acid. <span />
If you broke an element down to its smallest particles you would get an atom.
