How many moles of tin atoms are in a pure tin cup with a mass of 37.6 g ?

1 answer:

3 0

Tin is an element called Stannum and has the symbol Sn. Molar mass is the mass of 1 mol of a compound, 1 mol of any substance is made of 6.022 x 10²³ units, these units could be atoms making up an element or molecules making up a compound.
While the number of atoms making up 1 mol is the same for any element, the weight of 1 mol of substance varies from one another.
In tin(Sn) molar mass - 118.71 g/mol
In 118.71 g - there's 1 mol of tin
therefore in 37.6 g of tin - 1 x 37.6 / 118.71 = 0.31 mol
In 37.6 g of tin, there's 0.31 mol

How many grams are in 3.45 moles CO2

<h3>Hello There!!</h3>

<u> To Find:-</u>

Grams Present in 3.45 Moles of Carbon.

<u>We </u><u>Know:</u><u>-</u>

Molecular Mass of Carbon Dioxide= 44.01 grams/mol or 44 grams/mol

$\text{Moles} = \frac{\text{Mass}}{\text{Molecular mass}}$

$\implies 3.45 \text{moles} = \frac{ \text{Mass}}{44 \text{g/mol}} \\ \\ \implies \text{Mass} = {44 \text{g/mol}} \times 3.45 \text{moles} \\ \\ \implies \text{Mass} = {44 \text{g/} \cancel\text{ mol}} \times 3.45 \cancel\text{moles} \\ \\ \implies \text{Mass} = 44 \text{g} \times 3.45 \\ \\ \implies \text{Mass} = \red{151.8 \text{g}}$

$\therefore \text{Mass of 3.45 Moles of Carbon Dioxide is = \red{151.8g}}$

How could both phone and tv break in the collision?

Alina [70]

Answer:

You could trip down and fall with your phone in your hand, however by accident you may throw your phone before hitting the ground to crack it and when you throw the phone, you could have directly thrown it at the tv and then the phone bounced off the tv caused by impact and hit the ground harshly causing the phone and tv to crack or break in the process and to add you might be also, hurt from the fall. Hope this helps :)

Use you observation to determine which polymorph is in the customer’s returned chocolate sample.

Butoxors [25]

Answer:

Cocoa butter, the fat in chocolate, can crystallize in any one of 6 different forms (polymorphs, as they are called). Unfortunately, only one of these, the beta crystal (or Form V), hardens into the firm, shiny chocolate that cooks want. Form VI is also a stable hard crystal, but only small amounts of it form from the good beta (Form V) crystals upon lengthy standing. When you buy commercial chocolate it is in the form of beta crystals.

When you melt chocolate and get it above 94° F, you melt these much desired beta crystals and other types of crystals can set up. If you simply let melted chocolate cool, it will set up in a dull, soft, splotchy, disgusting-looking form. Even the taste is different. Fine chocolate has a snap when you break it and a totally different mouthfeel from the other cocoa butter forms.
