The different types of electromagnetic radiation shown in the electromagnetic spectrum consists of radio waves, microwaves, infrared waves, visible light, ultraviolet radiation, X-rays, and gamma rays.
Answer : Volume of HCl ( in ml) is 10 ml.
Solution : Given, Concentration of NaOH = 0.1 mol/L
Volume of NaOH = 20 ml
Concentration of HCl = 0.2 mol/L
Volume of HCl = ?
Formula used : Moles = Volume × Concentration
In the reaction, we see that 1 mole of NaOH react with the 1 mole of HCl.
so,
Moles of NaOH = Moles of HCl
Moles of HCl = Moles of NaOH = Volume of NaOH ( in L) × Concentration of NaOH
Converstion ml into L : 1000 ml = 1 L
Moles of HCl =
× 0.1
= 0.002 mol
Volume of HCl = Moles / Comcentration of HCl
= 
= 0.01 L
Volume of HCl (in ml) = 0.01 × 1000 = 10 ml
Hypothesis, experiment, conclusion<span />
The Molar mass of an atom corresponds directly with its atomic mass on the periodic table.
Hey there!
Volume in mL :
1.68 L * 1000 => 1680 mL
Density = 0.921 g/mL
Therefore:
Mass = density * Volume
Mass = 0.921 * 1680
Mass = 1547.28 g
