I think it would be ionization
Answer:
umm it does not show what elements but I think its C. number of protons
Answer:
262.8 g
Explanation:
Molarity = 3.0M
Mass = ?
Volume = 2.40L
The relationship between these quantities is given as;
Molarity = Number of moles / Volume
Number of moles = Molarity * Volume
Number of moles = 3 * 2.4 = 7.2 mol
Mass = Number of moles * Molar mass
Molar mass of HCl = 1 + 35.5 = 36.5 g/mol
Mass = 7.2 * 36.5 = 262.8 g
Answer:
1.5M
Explanation:
Molarity = moles/volume
0.60 mol / 0.40 L = 1.5 M
