How many moles of KF would need to be added to 2500 ml of water to make 1.2 M solution?

Oduvanchick [21]

The number of moles of KF needed to prepare the solution is 3 moles

<h3>What is molarity?</h3>

Molarity is defined as the mole of solute per unit litre of solution. Mathematically, it can be expressed as:

Molarity = mole / Volume

<h3>How to determine the mole of KF </h3>

Volume = 2500 mL = 2500 / 1000 = 2.5 L
Molarity = 1.2 M
Mole of KF =?

Molarity = mole / Volume

1.2 = mole of KF / 2.5

Cross multiply

Mole of KF = 1.2 × 2.5

Mole of KF = 3 moles

Put these different types of radiation in order from MOST to LEAST penetrating.

Naily [24]

Answer:

C. Gamma > beta > alpha

Explanation:

<u>Alpha rays</u> : These are positively charged and have mass 4u. These contain high energy Helium nucleus with 2 proton and 2 neutron.

These are heavier and maximum charged than beta and gamma particles.They have low velocity,least penetration power (can't travel more than 10-18 cm).

<u>Beta rays</u> : They are negatively charged and have negligible mass.

On emmission of beta particle, neutron is divided into proton and electron. They have less mass and very high velocity, so their penetrating power is more than alpha particles.

<u>Gamma rays</u>: These are parts of electromagnetic spectrum and travel with the speed of light (maximum velocity).Gamma rays do not have mass have maximum penetrating power.
