Question

b. 2g NaOH in 50ml solution with full solution​

Answer 1

Answer:

here is your ans

Explanation:

Concentration of NaOH in gL-¹

=Mass of NaOH in gram/volume of NaOH in litre

=2×1000/50

=40gL-¹

In terms of gram per litre :

2 g of NaOH in 50 mL has concentration = 40gL−1 

Molecular mass of NaOH = 23 + 16 + 1 = 40

Molarity=mass of volume in moles/volume of NaOH in L

=2×1000/40×50

=1mol L-¹

In terms of moles per litre:

2 g of NaOH in 50 mL has concentration = 1mol L−1
