How many moles are in 325 mL Ne at STP?
Slav-nsk [51]

Hey there!

325 mL in liters:

325 / 1000 => 0.325 L

1 mole ( Ne ) ------------- 22.4 L ( at STP )

moles ( Ne ) ------------ 0.325 L

moles Ne = 0.325 * 1 / 22.4

moles Ne = 0.325 / 22.4

moles Ne = 0.0145 moles

hope this helps!

You have 180 g of radium that takes up 36 cm ^ 3 of space if you were to cut it in half and have only 90 g
Leno4ka [110]

If you were to cut the radium  in half and have only 90 g, it will take up 18 cm³.

<h3>What is density?</h3>

The density of an object is the ratio of mass to volume of object.

Density = mass/volume

volume = mass/density

at a constant density, the volume of an object is proportional to its mass.

From the question, you have 180 g of radium that takes up 36 cm ^ 3 of space if you were to cut it in half and have only 90 g, the new mass will take the following volume.

180 g = 36 cm³

90 g =  ?

= (90 x 36) / 180

= 18 cm³

Thus, if you were to cut the radium  in half and have only 90 g, it will take up 18 cm³.

A patient needs to take 875mg twice daily The pills in the bottle are each 250mg How many pills does she wants to take 875mg
Angelina_Jolie [31]

Answer:

3.5 pill need to taken for completing dosage of 875 mg

Explanation:

Total dosage of medicine to be taken in a day

= 2 * 875 \\= 1750mg

Total weight of one pill = 250 mg

Number of pills required is equal to total dosage of medicine divided by the weight of one pill.

Hence,

Number of pills

= \frac{875}{250} \\= \frac{175}{50} \\= \frac{35}{10} \\= 3.5
