How many molecules are contained in 0.254 moles of diarsenic trioxide

SIZIF [17.4K]

Answer:

1.53 × 10²³ molecules As₂O₃

Explanation:

Step 1: Define

Diarsenic Trioxide - As₂O₃

Avagadro's number: 6.02 × 10²³ atoms, molecules, formula units, etc.

Step 2: Use Dimensional Analysis

$0.254 \hspace{3} mol \hspace{3} As_2O_3(\frac{6.02(10)^{23} \hspace{3} molecules \hspace{3} As_2O_3}{1 \hspace{3} mol \hspace{3} As_2O_3} )$ = 1.52908 × 10²³ molecules As₂O₃

Step 3: Simplify

We have 3 sig figs.

1.52908 × 10²³ molecules As₂O₃ ≈ 1.53 × 10²³ molecules As₂O₃

) A children’s liquid cold medicine has a density of 1.23 g/mL. If a child is to take 2.5 tsp in a dose, what is the mass in gra

vekshin1

The relation between density and mass and volume is

$Density=\frac{Mass}{volume}$

the dose required is 2.5 tsp

each tsp contain 5mL

So dose required in mL = 2.5 X 5 = 12.5 mL

the mass will be calculated using following formula

$Mass=DensityXvolume$

$Mass=1.23\frac{g}{mL}X12.5mL= 15.38g$

The mass of dose in grams will be 15.38 g
