Answer:
The first molecule Avogadro constant is given as 6.022 X 10∧23/ mol
Explanation: Avogadro constant is the constituent particles of molecules, atoms and ions that make up a mole of an element or compound. Therefore, CO2 comprises one molecule, which is equivalent to 6.022 X 10∧23/ mol.
2 lone pair on phosphorus
Answer:
Volume occupied by oxygen gas at 15 degree centigrade is equal to centimeter cube
Explanation:
Assuming Pressure is constant.
where T1 and T2 are temperature in Kelvin
Substituting the give values we get-
Volume occupied by oxygen gas at 15 degree centigrade is equal to centimeter cube
Answer:el número de masa es la suma de los protones y neutrones en un átomo y el número atómico es sólo el número de protones.
Explanation:
Answer:
<em><u>= 0.1 M </u></em>
Explanation:
450mL = 0.45L
If 24g of a solute are weighed by 1 mole of solute
1.2g of a solute will be weighed by ( 1.2 ÷ 24 )
=<u> 0.05 moles of a solute.</u>
0.45L of a solution are occupied by 0.05 moles
1L will be occupied by ( 1÷0.45 ) × 0.05
= 0.1 M
