A chemist adds 135.0 mL of a 0.21M zinc nitrate (Zn(NO3) solution to a reaction flask. Calculate the mass in grams of zinc nitra

yKpoI14uk [10]

Answer:

5.36 grams the mass in grams of zinc nitrate the chemist has added to the flask.

Explanation:

$Molarity=\frac{\text{Moles of solute}}{\text{Volume of the solution (L)}}$

Moles of zinc nitrate = n

Volume of the solution = 135.0 mL = 0.1350 L

Molarity of the solution = 0.21 M

$0.21 M=\frac{n}{0.1350 L}$

$n=0.21M\times 0.1350 L=0.02835 mol$

Mass of 0.02835 moles of zinc nitrate:

0.02835 mol × 189 g/mol = 5.358 g ≈ 5.36 g

5.36 grams the mass in grams of zinc nitrate the chemist has added to the flask.

Marysya12 [62]

Answer:

Melting of ice

Explanation:

A physical change is one in which just the physical properties of the matter is altered. Most phase changes reaction falls under this type of change.

Examples are boiling, melting, freezing, condensation, sublimation, magnetization of metals, breaking glass, cutting wood.

No new kinds of matter is formed.
The process is reversible
No change in mass

Phoenix [80]

Answer:

Here's the conversion factor you need:

1 Kilometer = 39370 inches

So, for your question we want to go 405,696 km....

405696 km x 39370 inches/ 1 km = 15972283464 inches

15972283464 inches x 2.54 x10^8 atoms/1 inch = 4.05 x 10^18 atoms
