Question

You opened up a new 500. mL bottle of RobitussinTM. The dosage is 1.1 tablespoon (TBS).

How many doses are in the bottle?


1 tsp. = 4.93 mL
3 tsp. = 1 TBS.

b)What is the mass of 35.2 mL of a saline (salt water) solution that has a density of 1.12 g cm−3?

Answer 1

30.73 Doses and 39.42 g

Step-by-step explanation:

It is necessary to know the conversion factors in that manner change the initial 500 mL to the number of doses as follow:

`500 ml * (1tsp)/(4.93mL) * (1TBS)/(3tsp) * (1 Dose )/(1.1 TBS) = 30.7 doses\\`

And the for b. it is such necessary to take in account that 1 mL = 1
`cm^(3)`

35.2 mL * 1.12
`(g)/(cm^(3) )` = 39.42 g
