Answer:

The volume of sample at STP is = 41.22 ml

Explanation:

Given data

P_{1} = 0.9 atm

V_{1} = 50 ml

T_{1} = 298 K

At STP

P_{2} = 1 atm

T_{2} = 273 K

From ideal gas equation

\frac{P_1(V_1)}{T_1} = \frac{P_2(V_2)}{T_2}

\frac{(0.9)(50)}{298} = \frac{(1) V_2}{273}

V_2 = 41.22 ml

Therefore the volume of sample at STP is = 41.22 ml

Un átomo X posee 29 protones y de carga +2 ¿Cuántos electrones tiene?
lesya [120]

Responder:

27

Explicación:

Dado que:

Número de protones en el átomo X = 29

Carga en el átomo X = +2

Si no hay cargo neto;

número de protones = número de electrones

Sin embargo, dado que el átomo X tiene una carga de +2 (dando 2 electrones).

Por lo tanto,

Número de electrones = número de protones - número de carga en el átomo)

Número de electrones = (29 - 2) = 27

A reaction produces 0.883 moles of H₂O. How many molecules are produced?
prisoha [69]
The answer is 5.32 × 10²³ molecules

<span>Avogadro's number is the number of units (atoms, molecules) in 1 mole of substance:
</span>6.023 <span>× 10²³ units per 1 mole

We have 0.883 moles.
If 1 mole has </span>6.023 × 10²³ molecules, 0.883 moles will have x molecules:
1 mole : 6.023 × 10²³ molecules = 0.883 moles : x

x = 6.023 × 10²³ molecules * 0.883 moles : 1 mole = 5.32 × 10²³ molecules
