In making her morning tea, Dorothy drops a sugar cube into some hot water. She stirs the mixture but no longer sees the sugar cu
Kryger [21]

Answer:

Hydrophilic

Explanation:

A hydrophilic substance is any substance that interacts efficiently with water.

Since water is a polar solvent, a hydrophilic substance must also be polar in order to interact with water since like dissolves like in chemistry.

The fact that sugar disappears in hot water indicates that sugar is a polar hydrophilic substance because only a polar solute can dissolve in water

How<br>many mols are in 151 g of dinitrogen monoxide? ​
oksano4ka [1.4K]

Answer:

3.43 moles

Explanation:

To convert moles into grams you must take the number of grams and divide it by the atomic mass of the compound.

in this case, grams is 151 and N2O has an atomic mass of 44.013

so your equation would look like

151/44.013=3.430804535

your answer would be 3.43 moles

How many moles of Carbon are in 3.06 g of Carbon
natta225 [31]

Answer:

\boxed {\boxed {\sf 0.255 \ mol \ C }}

Explanation:

If we want to convert from grams to moles, the molar mass is used. This is the mass of 1 mole. They are found on the Periodic Table as the atomic masses, but the units are grams per mole (g/mol) instead of atomic mass units (amu).

Look up the molar mass of carbon.

  • Carbon (C): 12.011 g/mol

Set up a ratio using the molar mass.

\frac {12.011 \ g \ C}{ 1 \ mol \ C}

Since we are converting 3.06 grams to moles, we multiply by that value.

3.06 \ g \ C*\frac {12.011 \ g \ C}{ 1 \ mol \ C}

Flip the ratio. This way, the ratio is still equivalent, but the units of grams of carbon cancel.

3.06 \ g \ C* \frac{1 \ mol \ C}{12.011 \ g\ C}                      

3.06 * \frac{1 \ mol \ C}{12.011 }    

\frac {3.06}{12.011 } \ mol \ C                                

0.25476646 \ mol \ C

The original measurement of grams (3.06) has 3 significant figures, so our answer must have the same. For the number we calculated, that is the thousandth place.

  • 0.25476646

The 7 in the ten-thousandth place tells us to round the 4 up to a 5.

0.255 \ mol \ C

3.06 grams of carbon is approximately <u>0.255 moles of carbon.</u>
