Answer:
Molarity = 1 mol.L⁻¹
Solution:
Molar concentration (Molarity) is given as,
Molarity = Moles / Volume of Solution ------ (1)
Data Given;
Moles = 4 mol
Volume = 4 L
Putting Data in Eq. 1,
Molarity = 4 mol ÷ 4 L
Molarity = 1 mol.L⁻¹
Answer:
3
Explanation:
left side has 2 N so right side must have a 2 which means 6 H on right side so to get 6 on left you have a coef. of 3 to make 6 H
