4 moles of sugar.

Explanation:

A mole is defined as the amount of a substance contained in Avogadro's number of particles 6.02 x 10²³.

1 mole of substance = 6.02 x 10²³. molecules

Given that;

the sample of sugar contains 1.505 x 10²³.molecules

The number of moles in this amount of sugar is 4 moles

Mademuasel [1]

Answer:

$hello \: your \: answer \: is \: here.$

Explanation:

<h2>Condensation is the change of water from its gaseous form (water vapor) into liquid water. Condensation generally occurs in the atmosphere when warm air rises, cools and looses its capacity to hold water vapor. As a result, excess water vapor condenses to form cloud droplets.</h2>

At 3 atm pressure the volume of gas is 1200ml. What pressure is required to reduce the volume of the gas to 300ml if the tempera

Rufina [12.5K]

States that when a gas is held at a constant temperature and mass in a closed container, the volume and pressure vary inversely. The equation to use is P1V1=P2V2.

Given
V1=200mL×1L1000mL=0.2 L
P1=700 mmHg
V2=100mL×1L1000mL=0.1 L

Unknown
P2

Equation
P1V1=P2V2

Solution
Rearrange the equation to isolate P2 and solve.

P2=P1V1V2

P2=(700mmHg×0.2L)0.1L=1400 L, which must be rounded to 1000 L because all of the measurements have only one significant figure.

<h3>Boyle's law</h3>

According to Boyle's law, the pressure of a gas is inversely proportional to its volume, provided that the temperature is constant.

This can be mathematically represented as: P1V1 = P2V2

In this case, P1 = 759.4 torr, P2 is what we are looking for, V1 = 97.6 mL, and V2 = 146.6 mL

Hence, P2 = P1V1/V2 = 759.4x97.6/146.6 = 505.58 torr
