Question

What is the mass in grams of 0.802 mol of salicylic acid

Answer 1

Answer:

110.676 gm

Explanation:

wt of salicylic acid = 0.802 x m wt

                                = 0.802 x 138

                                 = 110.676 gm

Answer 2

The mass of 0.802 mol of salicylic acid is 110.77 grams.

• Given data :

Compound = Salicylic Acid.

Amount = 0.802 mol

• From,the mathematical calculations we get that the molecular weight of the salicylic acid is approximately 138.12 g/mol.

• We,know that the molecular weight is the value of mass of one mole amount of a chemical compound.

• So,

1 mole salicylic acid's mass = 138.12 g

0.802 mole salicylic acid's mass = 138.12×0.802 = 110.77 grams (approx.)

So,the mass of 0.802 mole of salicylic acid is 110.77 grams. (Answer)
