1. 5 moles

2. 75.6 grams

3. 2 moles

4.  1.806 x 10²⁴ particles

<h3>Further explanation</h3>

Given

mass and moles of compound

Required

mass, moles and number of particles

Solution

1. 530 g Na2CO3

mol = 530 g : 106 g/mol

mol = 5

2. 4.2 moles H2O

mass = 4.2 moles x 18 g/mol

mass = 75.6 grams

3. 12.04 x 10²³ O2

mol =   12.04 x 10²³ : 6.02  x 10²³

mol = 2

4. 3 moles of Mg

particles = 3 x 6.02  x 10²³

particles = 1.806 x 10²⁴

A balloon is filled to a volume of 1.50 L with 3.00 moles of gas at 25 °C. With pressure and temperature held constant, what wil
Ludmilka [50]

Answer:

Volume : 1.25 L

Explanation:

We are given here that the volume ( V_1 ) = 1.50 Liters, the initial moles ( held at 25 °C ) = 3.00 mol, and the final moles ( n_2 ) = 3.00 - 0.5 = 2.5 mol. The final mol is calculated given that 0.50 mol of gas are released from the prior 3.00 moles of gas.

Volume ( V_1 ) = 1.50 L,

Initial moles ( n_1 ) = 3.00 mol,

Final Volume ( n_2 ) = 3.00 - 0.5 = 2.5 mol

Applying the combined gas law, we can calculate the final volume ( V_2 ).

P_1V_1 / n_1T_1 = P_2V_2 / n_2T_2 - we know that the pressure and temperature are constant, and therefore we can apply the following formula,

V_1 / n_1 = V_2 / n_2 - isolate V_2,

V_2 = V_1 n_2 / n_1 = 1.50 L * 2.5 mol / 3.00 mol = ( 1.5 * 2.5 / 3 ) L = 1.25 L

The volume of the balloon will be 1.25 L.
