How many moles of water are in a beaker with 50 mL?

Chemistry
1 answer:
tatiyna3 years ago
5 0

Answer:

Number of moles = 2.8 mol

Explanation:

Given data:

Number of moles of water = ?

Volume of water = 50 mL

Density of water = 1.00 g/cm³

Solution:

1 cm³ =  1 mL

Density = mass/ volume

1.00 g/mL = mass/ 50 mL

Mass = 1.00 g/mL× 50 mL

Mass = 50 g

Number of moles of water:

Number of moles = mass/molar mass

Number of moles = 50 g / 18 g/mol

Number of moles = 2.8 mol

Illusion [34]

Answer:

I would say a cooled

Explanation:

because yeah it's going to be cold when it travels from Antarctica but then it's going on towards Africa and yeah the water is going to get warmth but it's going to cool the land of Antarctica because it's so dry and hot and humid but the water is going to be more warmed because Antarctica the water is freezing so you're trying to ask the temperature of the water it'd be more warm if you're trying to ask kind of like the temperature of the land it would be cooled

If there are 160 Calories in 28 g in 1 serving of Flamin' Hot Cheetos, how many gram(s) of Cheetos must you burn to raise the te
vagabundo [1.1K]

Answer:

3.5 g

Explanation:

The density of water is 1 g/mL. The mass (m) corresponding to 20.0 mL is 20.0 g.

We can calculate the heat (Q) required to raise the temperature of 20.0 mL of water 1 °C (ΔT).

Q = c × m × ΔT = 1 cal/g.°C × 20.0 g × 1 °C = 20 cal

where,

c is the specific heat capacity of water

There are 160 calories in 28 g of Cheetos. The mass that releases 20 cal is:

20 cal × (28 g/160 cal) = 3.5 g

A block made of a certain material has a thickness of 20 cm and a thermal conductivity of 0.04 m C. At a particular instant in t
amid [387]

Answer:

heat flux ( Q ) = 8 W/m³ uniform heat flux throughout the block

Explanation:

flat plate ecuation with uniform source:

  • d2T / dx² = - Q / k...........from general balance
  • if x = 0 ⇒ dT / dx = 0 ; Q = 0
  • if x = L ⇒ T = T1

∴ k = 0.04 W/mC;   L = 0.2 m

If T = - 100x² + 20x

⇒ dT / dx = - 200x + 20

⇒ d2T / dx² = - 200 = - Q / k

⇒ Q / k = 200

⇒ Q = 200 * 0.04 W/mC

⇒ Q = 8 W/m³
