Mass = molarity x molar mass( NaNO₃) x volume
mass = 1.50 x 85.00 x 4.50
mass = 573.75 g of NaNO₃
hope this helps!
Molar mass sucrose = 342.0 g/mol
V = 460 mL / 1000 = 0.46 L
Molarity = 1.10 M
mass = M * molar mass * V
mass = 1.10 * 342.0 * 0.46
mass = 173.052 g
hope this helps!
ANS: C = 85.63 %; H = 14.37 %
C = 2 x 12.01 u = 24.02 u
H = 4 x 1.008 u = 4.032 u
TOTAL = 28.052 u
% C = (24.02/28.052) x 100 % = 85.63 %
% H = (4.032/28.052) x 100 % = 14.37 %
<span>Scientists ignore the forces of attraction between particles in a gas under ordinary conditions</span><span> because the particles in a gas are apart and moving fast, rather than clustered and moving slow, therefore the forces of attraction are too weak to have a visible effect.</span>
Ions are Formed when atoms lose or gain electrons in order to fulfill the octet rule and have full outer valence electron shells.
