Question

n 1 L of Mannitol Salt Agar there are10 g of D-mannitol. Convert this to a weight over volume percentage (%w/v) and report your answer rounded to two decimal places. Do not include units in the answer block. Percent weight over volume (%w/v) is the weight of the solute in grams divided by the volume of the solvent in mL times 100. It is essentially expressing the grams of solute per 100 mL of solvent.

Answer 1

1.00 (%w/v)

Step-by-step explanation:

%w/v is an unit of concentration in chemistry defined as the ratio between mass of the solute in grams and volume of solvent in mL times 100.

In the problem, the solute is D-mannitol -Less quantity-. The mass of the solute is 10g

The volume of the solvent is 1L = 1000mL

Thus, %w/v is:

`(10g)/(1000mL) * 100` = 1.00 (%w/v)
