Hey there!
<span>Atomic Masses :
</span>
H = <span>1.00794 a.m.u
N = </span><span>14.0067 a.m.u
O = </span><span>15.9994 a.m.u
Therefore:
HNO3 = </span>1.00794 + 14.0067 + ( 15.9994 * 3 ) => <span>63.0128 g/mol</span>
It is the attraction between two atoms resulting from a redistribution of their outer electrons. Atoms form chemical bonds in order to make their outer electron shells more stable. Some resist due to some being very big and electronegative
Answer:
Number of moles = 0.99 mol
Explanation:
Given data:
Mass of potassium chloride = 74 g
Number of moles of potassium chloride = ?
Solution:
Formula:
<em>Number of moles = mass/molar mass</em>
Molar mass of KCl = 74.6 g/mol
now we will put the values in formula:
Number of moles = mass/molar mass
Number of moles = 74 g/ 74.6 g/mol
Number of moles = 0.99 mol
Answer:
If you want to calculate the wavelength of a wave, then all you have to do is plug the wave's speed and wave's frequency into the equation. Dividing speed by frequency gives you the wavelength
