How many moles in 843.211 grams of c6h12o6?
leonid [27]
Molar mass C6H12O6 = 12 x 6 + 1 x 12 + 16 x 6 = 180 g/mol

1 mole ------------ 180 g
( moles ) --------- 843.211 g

moles = 843.211 x 1 / 180

moles = 843.211 / 180

= 4,684 moles of C6H12O6

which of the following is an example of an electromagnetic wave A. an ocean wave B. A sound wave C. A light wave D. A wave trave
ruslelena [56]

Answer:

Light waves

Explanation:

It isn't sound because it isn't infrared, involve electromagneticism, or light/radiation. An ocean wave is a literal wave of water, and a wave traveling along a rope is way off course. Choose a light wave. Also, brainliest would be nice. Glad to help

A vessel contained N2, Ar, He, and Ne. The total pressure in the vessel was 987 torr. The partial pressures of nitrogen, argon,
xz_007 [3.2K]

Answer:

The partial pressure of neon in the vessel was 239 torr.

Explanation:

In all cases involving gas mixtures, the total gas pressure is related to the partial pressures, that is, the pressures of the individual gaseous components of the mixture. Put simply, the partial pressure of a gas is the pressure it exerts on a mixture of gases.

Dalton's law states that the total pressure of a mixture of gases is equal to the sum of the pressures that each gas would exert if it were alone. Then:

PT= P1 + P2 + P3 + P4…+ Pn

where n is the amount of gases present in the mixture.

In this case:

PT=PN₂ + PAr + PHe + PNe

where:

  • PT= 987 torr
  • PN₂= 44 torr
  • PAr= 486 torr
  • PHe= 218 torr
  • PNe= ?

Replacing:

987 torr= 44 torr + 486 torr + 218 torr + PNe

Solving:

987 torr= 748 torr + PNe

PNe= 987 torr - 748 torr

PNe= 239 torr

<u><em>The partial pressure of neon in the vessel was 239 torr.</em></u>
