0.5 moles of any gas is at STP, it will occupy how many LITERS of volume?
never [62]

Answer: 500L

Explanation:

No of moles= volume× molarity/1000

No of moles =0.5moles

Volume=?

Molarity of a gas at stp = 1M

Stp means standard temperature and pressure

No of moles = volume ×molarity/1000

Substitute the values

0.5=volume×1/1000

Cross multiply

Volume = 1000×0.5

Volume = 500L

The volume is 500L

A reaction produces 0.801 moles of H2O. How many molecules of H20 are produced?
timama [110]

Answer:

1 mole of molecules = 6.022 × 10²³ molecules

1 = 6.022 × 10²³ molecules / mole

Multiplying a number with [6.022 × 10²³ molecules / mole] is like multiplying the number with 1 so  0.877 mole × 6.022 × 10²³ molecules / mole = 5.28 × 10²³ molecules

5.28 × 10²³ molecules of water is produced.
