How many moles do we have if we have 7.02 x 1024 molecules of
Aloiza [94]

Answer:

10 moles of methane

Explanation:

1 mole of methane contains 6.02 × 10^23 molecules (Avogadro's number)

x moles should contain 7.02 x 1024 molecules of

methane

So,

x= 7.02 x 1024 × 1/6.02 × 10^23

x= 10 moles of methane

CAN SOMEONE PLEASE DO THIS FOR ME. ILL GIVE YOU BRAINLIEST AND A LOT OF POINTS. I NEED A STORY. (If you answer the question and
Ipatiy [6.2K]

I got an idea.

This will be a story. (comic can also be done with this. In fact it is better)

The title is the journey of the ice cube. (change it if you want)

Main character - ice cube

There was an ice cube made by the water from the freezer in an ice shop.

The ice cube, with a bunch of other ice cubes, were taken to be packed and sold to a restaurant. The ice cube was excited to where he was going while the other ice cubes are just meh. Now that the ice cubes arrived, a restaurant worker stores the ice cubes in a cooler and later used to put ice in a lemonade. While the lemonade in a glass cup was carried outside the porch of the restaurant by the waiter, the ice cube was fascinated by the environment of the restaurant. The waiter finally serves the thirsty customer and the customer drank almost half of the lemonade but the ice cube did not get in the man's mouth. Instead the other ice cubes went. The ice cube feared the person. Shortly after checking his phone, the customer was about to reach on to the glass until the hands accidentally pushes the glass over and falls. The ice cube and the remaining ice cubes spread away with the wasted lemonade liquid. No one bothered cleaning up the ice cubes, only the glass shards because the floor is a smooth concrete. Outside was really hot from the sun anyways so it would melt the ice cube and sooner evaporate. As it was in liquid form, the "ice cube" was feeling relaxed because it was just chilling on the floor. And when it evaporates, the ice cubes becomes more fascinated since it goes up to the sky while having a sky-view from above.

That is the end.

You can add, edit or even not consider this one. But this is just an example to spark up your ideas. Sorry if I made some English mistakes.

Hope that it helped

ANALO387: Percent Water in a Hydrate
mina [271]

Answer:

\large \boxed{37.77\,\%}}

Explanation:

(1) Mass of hydrate

\begin{array}{rcr}\text{Mass of crucible + hydrate} & = & \text{21.447 g}\\-\text{Mass of crucible} & = & \text{17.985 g}\\\text{Mass of hydrate} & = & \textbf{3.462 g}\\\end{array}

(2) Mass of water

\begin{array}{rcr}\text{Mass of crucible + hydrate} & = & \text{21.447 g}\\-\text{(Mass of crucible + anhydrous salt)} & = & \text{20.070 g}\\\text{Mass of water} & = & \textbf{1.377 g}\\\end{array}

(3) Percent of water

\begin{array}{rcl}\text{Percent of water}&=&\dfrac{\text{Mass of water}}{\text{Mass of hydrate}} \times 100 \%\\\\& = &\dfrac{\text{1.377 g}}{\text{3.462 g}} \times 100 \% \\\\& = &\mathbf{37.77 \%}\\\end{array}\\\text{The mass percent of water is $\large \boxed{\mathbf{37.77 \%}}$}
